drm/asahi: buffer: Complain more loudly about sync requests

This codepath is known broken and we have no plans to fix it. However,
it works most of the time, and it can work around bugs in the minimum
TVB size calculation formula. So if that ever happens, we still want it
to fix the problem, but complain loudly so we can fix the calculation.
