Keeping the priority low because of the very low occurence rate

I haven't been able to reproduce this on ICL. 

This was last seen on SKL:

Some fixes because this test was way too strict:

https://patchwork.freedesktop.org/series/59280/

It won't fix this bug, if the reason is that we stall longer than 16 ms, just make it less likely to occur.

This is not the goal of the test, the goal is just reducing runtime and improving test correctness.

The series landed:
 - @busy-flip-interruptible is gone
 - The '!(*v & flag)' assertion should now not be hit anymore

I have suppressed the test, waiting for another failure to come, so as I can update the filter. But since everything changed, this bug should be closed as it is not applicable to the newer IGT.

Closing as INVALID, since we don't have OUTDATED. Thanks!
