1. If CONFIG_SCHED_INSTRUMENTATION_SWITCH is enabled, then these additional interfaces are expected:
sched_note_suspend
sched_note_resume
at the same time，If CONFIG_SMP is enabled，then expected：
sched_note_cpu_pause
sched_note_cpu_paused
sched_note_cpu_resume
sched_note_cpu_resumed
2. other board if enable SCHED_INSTRUMENTATION，SCHED_INSTRUMENTATION_SWITCH to defconfig.
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()

in the handler, and the task also calls waitpid,
it will fail to delete the child function

If statement in line 103 could acces wdactivelist.head->lag when head was
NULL which could result in hard fault. The statement was also redundant
as the same condition is checked in the while loop below. This change
remove the if statement to prevent hard fault to occur.
