[libvirt] [PATCH 08/10] conf: Parse and validate disk source seclabels together with the source

[Peter Krempa]

Since seclabels are formatted along with the source element and will
also make sense to be passed for the backing chain we should parse them
in the place where we parse the disk source. Same applies for
validation.
