NFS: Clean up nfs4_find_state_owners_locked()
There's no longer a need to check the so_server field in the state owner, because nowadays the RB tree we search for state owners contains owners for that only server. Make nfs4_find_state_owners_locked() use the same tree searching logic as nfs4_insert_state_owner_locked().
