drm/mediatek: mtk_hdmi: Remove goto in mtk_hdmi_clk_enable_audio()

If the clk_prepare_enable() call for the SPDIF clock fails, just
disable and unprepare the clock in the error check branch and
return immediately instead of jumping to the end with a goto,
slightly reducing code size.

This commit brings no functional changes.
