Gao Xiang d8b7db6c50 sched/core: Add __sched tag for io_schedule() 
[ Upstream commit e3b929b0a1 ]

Non-inline io_schedule() was introduced in:

  commit 10ab56434f ("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.
