[libvirt] [[libvirt-glib PATCHv3] 1/3] Add proper error reporting to gvir_storage_vol_get_path

[Christophe Fergeau]

gvir_storage_vol_get_name currently call g_error when an error occurs.
Since g_error trigger a coredump, calling it in a library is harmful.
Replace this with proper GError error reporting.
