Instead of forcing a reprobe to handle copying the override_mode into default_mode, just change igt_output_get_mode() to return the override_mode if it's been set, and remove the old code which would directly overwrite default_mode. This should be more robust, as igt_output_get_mode() will always return the correct mode, without needing the output to be reprobed. This change means that output->config.default_mode always contains the "non-overridden" default mode.
