locks: New ops in lock_manager_operations for get/put owner
NFSD or other lockmanager may increase the owner's reference, so adds two new options for copying and releasing owner. v5: change order from 2/6 to 3/6 v4: rename lm_copy_owner/lm_release_owner to lm_get_owner/lm_put_owner Reviewed-by: Jeff Layton <jlayton@primarydata.com> Signed-off-by: Kinglong Mee <kinglongmee@gmail.com> Signed-off-by: Jeff Layton <jlayton@primarydata.com>
