to the big nfs4_lock_state removal around 3.17 (but that were also
probably hard to reproduce before client changes in 3.20 allowed the
client to perform parallel opens).
Also fix a 4.1 backchannel crash due to rpc multipath changes in 4.6.
Trond acked the client-side rpc fixes going through my tree.
