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().
