Todd Kjos 669d93f855 Revert "sched/core: Prevent race condition between cpuset and __sched_setscheduler()" 
This reverts commit 710da3c8ea.

When changing a thread's scheduling priority, binder calls
sched_setscheduler_nocheck() while holding the node lock and
proc inner lock. This was safe until v5.3 when this change was
introduced where cpuset_read_lock() is called in this path
which can sleep.

This patch was introduced to fix a possible accounting error
in sched deadline (potential oversell of CPU bandwidth) due
to a race condition between cpusets and __sched_setscheduler().
This is not an issue for Android.

This should be fixed in the binder driver, but that may take
some time.
