drm/mediatek: Fix config_updating flag never false when no mbox channel
When CONFIG_MTK_CMDQ is enabled, if the display is controlled by the CPU
while other hardware is controlled by the GCE, the display will encounter
a mbox request channel failure.
However, it will still enter the CONFIG_MTK_CMDQ statement, causing the
config_updating flag to never be set to false. As a result, no page flip
event is sent back to user space, and the screen does not update.
Fixes: da03801ad08f ("drm/mediatek: Move mtk_crtc_finish_page_flip() to ddp_cmdq_cb()")
