locks.c: add the fl_owner to nlm_compare_locks

Browse source 
Add the fl_owner to NLM compare locks. Since two different client can
present the same pid to the server it is not enough to distinguish locks
from different clients. The fl_owner field is a pointer to the struct
nlm_host which is unique for each client.
