Subject: [PATCH] ActionDestroyDevice should not obsolete ActionRemoveMember
If we want to remove a PV from a VG and then remove the PV device,
the ActionDestroyDevice must not obsolete the ActionRemoveMember
action. Eventhough we are going to remove the device, we still
need to call "vgreduce" first.
Resolves: rhbz#2076958
