From: Stanislav Kinsbursky <skinsbursky@xxxxxxxxxxxxx>
commit 88c47666171989ed4c5b1a5687df09511e8c5e35 upstream.
Since NFSd service is per-net now, we have to pass proper network
context in nfsd_shutdown() from NFSd kthreads.
The simplest way I found is to get proper net from one of transports
with permanent sockets.
