[libvirt] [PATCH 2/7] qemuDomainValidateStorageSource: Relax PR validation

[Michal Privoznik]

Actually, it is not always bug if path is provided. For instance,
on domain migration the migration XML contains the path even for
managed reservations. Accept this and teach our prepare code to
not leak in this case.
