Maxime Ripard 9649d08010 drm/tests: probe-helper: Fix drm_display_mode memory leak 
[ Upstream commit 8b6f2e2843 ]

drm_analog_tv_mode() and its variants return a drm_display_mode that
needs to be destroyed later one. The
drm_test_connector_helper_tv_get_modes_check() test never does however,
which leads to a memory leak.

Let's make sure it's freed.
