[Intel-gfx] [PATCH 3/3] drm/i915: Don't taint when using fault injection

[Michał Winiarski]

From: Michał Winiarski <michal.winiarski at intel.com>

It is not really unexpected to hit wedge on init this way.
We're already downgrading error printk when running with fault injection,
let's use the same approach for CI tainting.
