dm cache: add remove_cblock method to policy interface
Implement policy_remove_cblock() and add remove_cblock method to the mq
policy. These methods will be used by the following cache block
invalidation patch which adds the 'invalidate_cblocks' message to the
cache core.
Also, update some comments in dm-cache-policy.h
