Hello,

The 1st patch adds non_owner variants of start_freeze/unfreeze queue
API.

The 2nd patch applies the non_owner variants on nvme_freeze() & nvme_unfreeze(). 

The 3rd patch models freeze/enter queue as lock for lockdep support.

V2:
	- improve comment log & document(Christoph)
	- add reviewed-by tag
