[Xen-devel] [PATCH] libxl: set rc to 0 in init_acpi_config in success path

[Wei Liu <wei.liu2@xxxxxxxxxx>]

xc_doamin_getinfo returns >=0 in success path, and if there is no vnode
configured, that rc will be returned to caller, which indicates error.

Fix that by setting rc to 0 in success path.

Please squash this with "libxl: init_acpi_config should return rc
in exit path" when backporting to 4.8.
