[igt-dev] [PATCH i-g-t] lib: Fix interface descriptor fills

[Mika Kuoppala]

For gen8+ we need to increment the pointer for interface
descriptor size amount. Otherwise the next indirect item
introduced will overwrite our descriptor.

Apparently this has not caused much havoc as interface
descs has been the last item.
