[igt-dev] [PATCH i-g-t] tests/kms_cursor_legacy: Wait for an extra vblank

[Mika Kahola]

kms_cursor_legacy IGT subtest 2x-nonblocking-modeset-vs-cursor-atomic
is failing due to busyness while trying to do atomic commit. In case,
we are busy, let's just wait one extra vblank before continuing the
test.
