igt/kms_flip: Allow very large bo to fail pageflips with E2BIG
We tried to allow very large buffers (larger than the mappable aperture)
to be flippable by allowing them to be bound into the unmappable region.
Sadly, not all of our hw is capable of utilising the unmappable region for
scanout (and on some older hw, there is only mappable). As such, we have
to allow the very large bo to either succeed in being flipped, or fail
with the expected E2BIG.
