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.
