blk-mq: Rename blk_mq_update_tag_set_depth()

Browse Source 
The function does not set the depth, but rather transitions from
shared to non-shared queues and vice versa.

So rename it to blk_mq_update_tag_set_shared() to better reflect
its purpose.

[jpg: take out some unrelated changes in blk_mq_init_bitmap_tags()]
