This is just a testcase for a very specific lrc corner case. We do already
exercise lrc with all the other execbuf testcases. Imo we're covered
enough already with what we have in the basic testset - testing for all 3
billion cornercases will make it grow out of scope I fear. I'd just drop
this one here as not needed for BAT.

If you want to extend execbuffer scope a bit then we should add a
concurrency test, i.e. one of the gem_concurrent_blt testcases as basic
ones. Unfortunately to be able to reliable trigger race conditions those
all take a few seconds. But inter-batch sync is a _big_ gap across all
archs, and something which is even more tricky with lrc (and scheduler).
Imo that would be a lot more useful than this test here.
