[igt-dev] [PATCH i-g-t 2/2] Revert "tests/kms_invalid_mode: Test Cleanup"

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

This reverts commit 6725767a84109e934ca138d94df0482386c44532.

This was no cleanup. It does fifteen different things and
in the process flat out breaks the test at least on all
non-atomic drivers/platforms.
