Add TUNSETCARRIER ioctl, then we may change the carrier state of TUN dynamically. Note that we don't need an ioctl for getting carrier, it can be done by SIOCGIFFLAGS already.

If failed in pty_register2, it is possible to enter unregister_driver
function, which eventually calls ptmx_minor_free, resulting in mutex
conflict.

if dev->d_flags is POLICY_1, the circbuf cannot be initialized incorrectly.
We determine whether the circbuf should be initialized based on first reference on device and d_buffer is NULL

From the current implementation,udp localsoket receiver's pipe is closed, the sender write failed in the pipe;
we change the implementation to check if buffer is free(PIPE_IS_POLICY_0),if not free,the sender could write in the pipe;

Then, you will see the pipe hasn't free its resource, memleak
Resolve:
replace the inode refs with priv refs

Some macro definitions have already been defined in other header files, redundant macro definitions have been removed in include/nuttx/can.h. Align some code. Remove no use struct (can_response_s) and some variables.

below command to create mbim NIC on host
nsh> conn 3
NuttX's MBIM device implementation adds an additional MBIM network
card to the NuttX system, which can debug the data communication with
the host, but this network card is unnecessary and needs to be removed
when the business actually uses this driver, And the cdcncm_receive
method needs to be re-implemented.

Summary:
1. use nuttx/atomic.h instead of stdatomic
2. remove CONFIG_HAVE_ATOMIC,because we now support atomic on all platforms
