scsi: Remove a blk_mq_run_hw_queues() call
blk_mq_kick_requeue_list() calls blk_mq_run_hw_queues() asynchronously.
Leave out the direct blk_mq_run_hw_queues() call. This patch causes
scsi_run_queue() to call blk_mq_run_hw_queues() asynchronously instead
of synchronously. Since scsi_run_queue() is not called from the hot I/O
submission path, this patch does not affect the hot path.
This patch prepares for allowing blk_mq_run_hw_queue() to sleep if
BLK_MQ_F_BLOCKING has been set. scsi_run_queue() may be called from
atomic context and must not sleep. Hence the removal of the
blk_mq_run_hw_queues(q, false) call. See also scsi_unblock_requests().
