scsi: ufs: core: Set task state before io_schedule_timeout()

Browse source

Set the task state to TASK_UNINTERRUPTIBLE before calling
io_schedule_timeout() in ufshcd_wait_for_pending_cmds().  Without
setting the task state, io_schedule_timeout() returns immediately
because the task state remains TASK_RUNNING. This results in a busy loop
that wastes CPU cycles.
