passthrough/domctl: use correct struct in union

This appears to be a copy paste error from c/s 23861:ec7c81fbe0de.

It is safe, functionally speaking, as both the xen_domctl_assign_device
and xen_domctl_get_device_group structure start with a 'uint32_t
machine_sbdf'.  We should however use the correct union structure.
