rbd: make get_lock_owner_info() return a single locker or NULL

commit f38cb9d9c2045dad16eead4a2e1aedfddd94603b upstream.

Make the "num_lockers can be only 0 or 1" assumption explicit and
simplify the API by getting rid of output parameters in preparation
for calling get_lock_owner_info() twice before blocklisting.
