vhd-util scan can crash when ran against a VHD with a corrupt footer. Happens when the footer reports a VHD type that should have a parent (like HD_TYPE_DIFF) while having none, causing the segfault. Signed-off-by: Mathieu Labourier <mathieu.labourier@vates.tech>

vhd-util scan can crash when ran against a VHD with a corrupt footer.
Happens when the footer reports a VHD type that should have a parent (like HD_TYPE_DIFF) while having none, causing the segfault.
This fix also escalates the error in vhd_util_scan_get_volume_parent
which was not done before.
