From: Michał Winiarski <michal.winiar...@intel.com>
Since:
0d4b78b3d2c0 ("drm/i915/guc: Assert we have the doorbell before setting it up")
We have asserts in GuC doorbell related functions, which is a good thing.
Unfortunately, we were using those to check whether GuC FW is refusing
to allocate invalid doorbell - which makes the test fail.
Well, it would make the test WARN, except we fumbled cleanup ordering
and eat the BUG_ON instead.
Let's keep the asserts and use the internal implementation in the test.
