6.14-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit dacafdcc7789cfeb0f0552716db56f210238225d ]
drm_mode_find_dmt() returns a drm_display_mode that needs to be destroyed later one. The drm_test_pick_cmdline_res_1920_1080_60() test never does however, which leads to a memory leak.
Let's make sure it's freed.
