NFSv4: Fix another nfs4_sequence corruptor
commit b7e63a1079b266866a732cf699d8c4d61391bbda upstream.
nfs4_release_lockowner needs to set the rpc_message reply to point to
the nfs4_sequence_res in order to avoid another Oopsable situation
in nfs41_assign_slot.
Fixes: fbd4bfd1d9d21 (NFS: Add nfs4_sequence calls for RELEASE_LOCKOWNER)
Cc: stable@vger.kernel.org # 3.12+
