Subject: drm/i915/selftests: Allow random array allocation to fail
Git-commit: 9861b6682804a9db82600e0adf592bfa6deec377
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

In the selftests, we don't want to force an oom and would rather
ENOMEM be reported. In this case, we would rather the allocation for the
random array to fail.
