drm/i915: Don't add panel_fixed_mode to the probed modes list at LVDS init.
In the case where no EDID data is read from the device, adding the panel_fixed_mode pointer to the probed modes list causes data corruption. If the panel_fixed_mode pointer is added to the probed modes list at init time, a copy of the mode is added again at drm_get_modes() request time. Then, the panel_fixed_mode pointer is freed because it is seen as a duplicate mode. Unfortunately, this pointer is still stored and used in mode_fixup(). Because the panel_fixed_mode data is copied and returned at drm_get_modes() time, it is unnecessary to add this information at init time.
