Without this patch, the following assertion may be hit:
xl: libxl_create.c:589: libxl__domain_make: Assertion `info->passthrough !=
LIBXL_PASSTHROUGH_ENABLED' failed.
This is because libxl__domain_create_info_setdefault() currently only sets
an appropriate value for 'passthrough' in the case that 'cap_hvm_directio'
is true, which is not the case unless an IOMMU is present and enabled in
the system. This is normally masked by xl choosing a default value, but
that will not happen if xl is not used (e.g. when using libvirt) or when
a stub domain is being created.
