[PATCH][linux-lts-utopic] Fix regression starting unprivileged lxc containers

[Seth Forshee]

== SRU Justification ==

Impact: linux-lts-utopic 3.16.0-46.62 contains a regression which prevents
unprivileged containers from starting due to a failure mounting sysfs.

Fix: Backport of upstream commit 7236c85e1be51a9e25ba0f6e087a66ca89605a49,
which is marked for stable but is missing from 3.16 stable. Another stable
commit that did get into 3.16 requires this patch.

Regression potential: This patch is specifically targeted at unprivileged
mounts of virtual filesystems in containers and fixes a regression there. It
should have no impact on mounts in the host.

Thanks,
Seth
