sched, cleanup, treewide: Remove set_current_state(TASK_RUNNING) after schedule()
schedule(), io_schedule() and schedule_timeout() always return
with TASK_RUNNING state set, so one more setting is unnecessary.
(All places in patch are visible good, only exception is
kiblnd_scheduler() from:
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c
Its schedule() is one line above standard 3 lines of unified diff)
No places where set_current_state() is used for mb().
