nfsd: pass proper net to nfsd_destroy() from NFSd kthreads
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. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: J.
