block: move blk_mq_add_queue_tag_set() after blk_mq_map_swqueue()
Move blk_mq_add_queue_tag_set() after blk_mq_map_swqueue(), and publish
this request queue to tagset after everything is setup.
This way is safe because BLK_MQ_F_TAG_QUEUE_SHARED isn't used by
blk_mq_map_swqueue(), and this flag is mainly checked in fast IO code
path.
Prepare for removing ->elevator_lock from blk_mq_map_swqueue() which
is supposed to be called when elevator switch can't be done.
