mmc: core: kick block queue after unhalting cmdq
If request has to be requeued due to cmdq being halted and if we change
the task status to interruptible before going to sleep then cmdq thread
may not wakeup again. Note that blk_requeue_request() doesn't trigger
->request_fn() again to wakeup the cmdq thread.
Fix this issue by kicking the queue once cmdq state machine is unhalted.
