nfsd: fix vm overcommit crash fix #2

The previous patch from Alan Cox ("nfsd: fix vm overcommit crash",
commit 731572d39fcd3498702eda4600db4c43d51e0b26) fixed the problem where
knfsd crashes on exported shmemfs objects and strict overcommit is set.

But the patch forgot supporting the case when CONFIG_SECURITY is
disabled.

This patch copies a part of his fix which is mainly for detecting a bug
earlier.
