[Intel-gfx] [PATCH i-g-t 2/3] tests/kms_cursor_legacy: Perform lazy cleanup between tests

Instead of assuming each subtest cleans up after itself, assume it
fails and doesn't. Now that igt_kms can clean up stale events, we
can just force each subtest to only clean up its framebuffers,
which isn't harmful if it failed.
