This change reflects that the geometry isn't related to the largest
allocatable unit on the platform.
Calls to read and write block devices are also affected and have
been updated.
Right now if usb tracing is enabled but verbose is disabled
a debug assert will be triggered when ever a verbose trace point
is hit. Instead of trying to print the NULL message, just return
early.

There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!

malloc() and free() should never be used within the OS. This will work in the FLAT build because there is only a single heap, but will cause problems in PROTECTED and KERNEL build modes where there are separate heaps for user and kernel memory.
Typically kmm_malloc(), kmm_zalloc(), and kmm_free() should be called within the kernel in those build modes to use the kernel heap.
Memory is never free. Possible memory leak:
./boards/arm/cxd56xx/common/src/cxd56_crashdump.c: pdump = malloc(sizeof(fullcontext_t));
Memory allocated with malloc(), but freed with kmm_free():
./drivers/usbhost/usbhost_composite.c: cfgbuffer = (FAR uint8_t *)malloc(CUSTOM_CONFIG_BUFSIZE);
Memory is never freed in these cases. It is allocated in the driver initialization logic, but there is no corresponding uninitialization logic; memory is not freed on error conditions:
./arch/arm/src/lc823450/lc823450_i2s.c: priv = (struct lc823450_i2s_s *)zalloc(sizeof(struct lc823450_i2s_s));
./arch/arm/src/sam34/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
./arch/arm/src/sama5/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
./arch/arm/src/samv7/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
Memory is allocated with zalloc() but freed on error conditions with kmm_free():
./arch/arm/src/sama5/sam_ssc.c: priv = (struct sam_ssc_s *)zalloc(sizeof(struct sam_ssc_s));
./arch/arm/src/samv7/sam_ssc.c: priv = (struct sam_ssc_s *)zalloc(sizeof(struct sam_ssc_s));
./arch/arm/src/stm32/stm32_i2s.c: priv = (struct stm32_i2s_s *)zalloc(sizeof(struct stm32_i2s_s));
Memory is never freed:
./drivers/spi/spi_bitbang.c: priv = (FAR struct spi_bitbang_s *)zalloc(sizeof(struct spi_bitbang_s));

Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under drivers/usbhost.
