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.

Hi Sasha,

This is a prerequisite patch, it doesn't make sense to backport it
without also backporting "rbd: harden get_lock_owner_info() a bit" and
"rbd: retrieve and check lock owner twice before blocklisting".

Please drop it.

Thanks,

                Ilya
