3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stanislav Kinsbursky <skinsbursky@xxxxxxxxxxxxx>
commit f7fb86c6e639360ad9c253cec534819ef928a674 upstream.
There could be a situation, when NFSd was started in one network namespace, but
stopped in another one.
This will trigger kernel panic, because RPCBIND client is stored on per-net
NFSd data, and will be NULL on NFSd shutdown.
