Milan Broz e1b0dce76e Use PV UUID in hash for device name when exporting metadata.
Currently code uses pv_dev_name() for hash when getting internal
"pvX" name.

This produce corrupted metadata if PVs are missing, pv->dev
is NULL and all these missing devices returns one name
(using "unknown device" for all missing devices as hash key).
