[PATCH] Never activate hidden volumes directly in vgchange.

[Milan Broz <mbroz@redhat.com>]

Never activate hidden volumes directly in vgchange.

All hidden (not visible) volumes should be activated through
other visible volumes.

(There are already exceptions like snapshot, mirror log and image,
which should be cleaned one day...)

This solves problems for future types of hidden volumes,
which can have special meaning and must not be activated implicitly
(e.g. key store volume).
