Subject: [PATCH] dm: Fix comparing DM RAID member devices UUID

There is no "UUID" property in UDev we must use the "ID_FS_UUID"

one.

This comparison works only because most DM RAID members don't have

UUID so the check is skipped, but it fails for DDF RAID members

which have a special GUID/UUID in UDev database.
