sched: do not crash for priority multi-boost

Browse Source 
aio client will queue asynchronous io requests to the worker threads.
if PRIORITY_INHERITANCE is enabled, client thread's priority will be
set to worker threads. There will be multi-boost/restore of worker
threads' priority and assert the system.

No need priority multi-boot/restore to worker thread because client
thread's priority is alway the same.
