[libvirt] [PATCH 04/18] util: storage: Remove obsolete argument virStorageFileGetMetadataInternal

[Peter Krempa]

As we already pass the whole structure down the call path there's no
need to return some stuff in a separate argument. Remove the argument
and call tweakers to avoid breaking semantics.

virStorageFileGetMetadataFromBuf will be refactored later along with the
storage driver.
