drm/mediatek: fix mtk_hdmi_setup_vendor_specific_infoframe mistake

commit 014580ff upstream.

mtk_hdmi_setup_vendor_specific_infoframe will return before handle
mtk_hdmi_hw_send_info_frame.Because hdmi_vendor_infoframe_pack
returns the number of bytes packed into the binary buffer or
a negative error code on failure.
So correct it.
