drm/i915/selftests: Report ENOMEM clearly for an allocation failure If we can not run the drunk_hole test because we couldn't allocate the memory for the permutation array (even after we tried trimming the size), report a clear ENOMEM. Similary, if we are asked to operate on a hole too small for ourselves, make it skip quietly. v2: Avoid malloc(0) since that returns ZERO_SIZE_PTR not NULL. v3: Fixup similar construction for lowlevel_hole v4: Use u64 >> 1 to avoid 64b div.
