Subject: [PATCH] blk-mq: kick requeue list in blk_mq_requeue_request()

blk_mq_requeue_request() should kick off the requeue list so
that the request can be scheduled to queue finally.

In nvme conversion patch, blk_mq_requeue_request() is called
to requeue failed request from completion handler, this patch
fixes the issue and makes the block API working as expected.
