drm/i915/selftest: annotate maybe unused but set variable unused

Prepare for re-enabling -Wunused-but-set-variable.

The variable is indeed 'unused' as the name suggests, but we can't just
drop it because i915_vma_unbind_unlocked() is annotated
__must_check. Apparently the selftest does not really need to check the
value.
