aa94b5371f block: adjust tagging function queue bit locking 
For most initialization purposes, calling blk_queue_init_tags() without
the queue lock held is OK. Only if called for resizing an existing map
must the lock be held. Ditto for tag cleanup, the maps are reference
counted.

So switch the general queue flag setting to the unlocked variant, but
retain the locked variant for resizing.

75ad23bc0f block: make queue flags non-atomic 
We can save some atomic ops in the IO path, if we clearly define
the rules of how to modify the queue flags.

278caf0120 block/blk-tag.c should #include "blk.h" 
Every file should include the headers containing the externs for its
global functions (in this case for __blk_queue_free_tags()).
