Petr Rockai bf29eabdba lvmetad: Keep the cache consistent when a PV moves around.
In cases where PV appears on a new device without disappearing from an old one
first, the device->pvid pointers could become ambiguous. This could cause the
ambiguous PV to be lost from the cache when a different PV comes up on one of
the ambiguous devices.
