As kms_flip is using dynamic subtests, no need to trigger the skip 
(igt_subtest_with_dynamic will call igt_skip if no dynamic subtests 
executed).

So, just return if it is not an intel device.

+       if (flags & TEST_BO_TOOBIG && !is_intel_device(drm_fd))
+               return;

Also, do we need the same change for 2x tests too?
