ASoC: rockchip: spdif: Add missing clk_disable_unprepare() in rk_spdif_runtime_resume()

[ Upstream commit 6d94d0090527b1763872275a7ccd44df7219b31e ]

rk_spdif_runtime_resume() may have called clk_prepare_enable() before return
from failed branches, add missing clk_disable_unprepare() in this case.
