Subject: [PATCH] drm/i915/selftests: fix inconsistent IS_ERR and PTR_ERR

Fix inconsistent IS_ERR and PTR_ERR in shrink_boom.
The proper pointer to use is _explode_ instead of _purge_.

This issue was detected with the help of Coccinelle.

Fixes: fe215c8bc426 ("drm/i915/selftests: add missing gtt shrinker test")
