drm/i915/guc: Assert that we switch between known ggtt->invalidate functions

When we enable the GuC, we enable an alternative mechanism for doing
post-GGTT update invalidation. Likewise, when we disable the GuC, we
restore the previous method. Assert that we change between known
endpoints, so that we can catch if we accidentally clobber some other
gen and if we change the invalidate routine without updating guc.
