Yes, this is good place for assert.

While I agree I'm so-so about doing this change since it will follow
into massive patch for test which I'm anyway wanting to throw away in
the end.

No, here will arrive query for all fb formats which kernel talk about.
If bpp become zero this will go out from testing mode which is not
supported. Ie. C8 or XBGR2101010 will go forward and here other formats
are ditched.

I did consider this as too verbose. Above where crcs are compared
there's printed what failed with more detail than here.

I'm going to have few CI runs with evolving this patch still.
I found timing error on this test, it is most likely what is causing the
noise from this test in CI runs. I somehow never see it on any of my own
computers but realized it from the logic and first attempt to mitigate
it changed CI results for the better so I'll get that fixed.
