blk-mq: remove dead check from blk_mq_dispatch_rq_list
When BLK_STS_RESOURCE or BLK_STS_DEV_RESOURCE is returned from .queue_rq, the 'list' variable always holds this rq which isn't queued to LLD successfully. So blk_mq_dispatch_rq_list() always returns false from the branch of '!list_empty(list)'. No functional change.
