sched/core: Add __sched tag for io_schedule()
[ Upstream commit e3b929b0a184edb35531153c5afcaebb09014f9d ]
Non-inline io_schedule() was introduced in:
commit 10ab56434f2f ("sched/core: Separate out io_schedule_prepare() and io_schedule_finish()")
Keep in line with io_schedule_timeout(), otherwise "/proc/<pid>/wchan" will
report io_schedule() rather than its callers when waiting for IO.
