mmc: queue: fix the cmdq thread wake up handling
If request has to be requeued (due to any DCMD commmand pending or cmdq
being halted) and if we change the task status to interruptible before
going to sleep then thread may not wakeup again. Note that
blk_requeue_request() doesn't trigger ->request_fn() again to wakeup
the thread.
Fix this issue by making cmdq thread wait for the completion of DCMD
or until the cmdq is unhalted. This change also simplifies the
cmdq thread function.
