proc: fix /proc/net/* after setns(2)
[ Upstream commit 1fde6f21d90f8ba5da3cb9c54ca991ed72696c43 ]
/proc entries under /proc/net/* can't be cached into dcache because
setns(2) can change current net namespace.
[akpm@linux-foundation.org: coding-style fixes]
[akpm@linux-foundation.org: avoid vim miscolorization]
[adobriyan@gmail.com: write test, add dummy ->d_revalidate hook: necessary if /proc/net/* is pinned at setns time]
