Then again the test is only relevant for gen2/3 (and 1), and I don't
forsee the use of fences for GPU surface tiling being resurrected. On
the other hand, the test makes sure that future gpus ignore the old
restrictions.

One feature request for the test: feed in > max_fences expect
ENOSPC/EDEADLCK on gen2/3.
