[PATCH] drm/i915/selftest: Mark the mock struct file backpointer as invalid

[PATCH] drm/i915/selftest: Mark the mock struct file backpointer as invalid

[Chris Wilson]

We do not use the struct file backpointer so struct drm_file, so mark it
as invalid when creating a mock file for i915 selftests.

It is only used by legacy vm mmapping, not by i915.ko
