> 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.
