nfsd: only set file_lock.fl_lmops in nfsd4_lockt if a stateowner is found
nfsd4_lockt does a search for a lockstateowner when building the lock struct to test. If one is found, it'll set fl_owner to it. Regardless of whether that happens, it'll also set fl_lmops. Given that this lock is basically a "lightweight" lock that's just used for checking conflicts, setting fl_lmops is probably not appropriate for it. This behavior exposed a bug in DLM's GETLK implementation where it wasn't clearing out the fields in the file_lock before filling in conflicting lock info. While we were able to fix this in DLM, it still seems pointless and dangerous to set the fl_lmops this way when we may have a NULL lockstateowner.
