Subject: [PATCH 3.4 56/88] nfsd: pass net to nfsd_create_serv()

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stanislav Kinsbursky <skinsbursky@...allels.com>

commit 6777436b0f072fb20a025a73e9b67a35ad8a5451 upstream.

Precursor patch. Hard-coded "init_net" will be replaced by proper one in
future.
