102a6357ca Revert "sched: Remove a redundant critical section" 
There is a potential problem that can lead to deadlock at
condition wait, if the timeout of watchdog is a very small value
(1 tick ?), the timer interrupt will come before the nxsem_wait()

Revert "sched: pthread: Remove a redundant critical section in pthread_condclockwsait.c"
Revert "sched: semaphore: Remove a redundant critical section in nxsem_clockwait()"
Revert "sched: semaphore: Remove a redundant critical section in nxsem_tickwait()"
