[libvirt] [PATCH] Fix error message when failing to detect filesystem

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

If we looped through /etc/filesystems trying to mount with each
type and failed all options, we forget to actually raise an
error message.

* src/lxc/lxc_container.c: Raise error if unable to detect
  the filesystems. Also fix existing error message
