Summary:
- During investigating critical section with semaphores, I noticed
that nxtask_flushstreams() is called with a critical section.
- The function calls lib_flushall() which handles a semaphore
in userspace.
- So it should be done without a critical section
Impact:
- SMP only
Testing:
- Tested with ostest the following configs
- esp32-devkitc:smp (QEMU), sabre-6quad:smp (QEMU)
- maix-bit:smp (QEMU), sim:smp
- spresense:smp
- Tested with nxplayer and stress test with spresense:wifi_smp
