[Intel-gfx] [PATCH v2] drm/i915: Add a default case in gen7 hwsp switch-case

> Gen7 won't get any new engines, and we already added VCS2 there to just
> silence gcc's not handled in switch warnings.
> 
> Use a default case instead, otherwise we will need to keep adding extra
> cases if changes happen in the future.
> 
> v2: Since reaching the default case is impossible, use GEM_BUG_ON (Chris).
