Subject: [PATCH v2] ASoC: rockchip: spdif: Add missing clk_disable_unprepare() in rk_spdif_runtime_resume()

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

Fixes: f874b80e1571 ("ASoC: rockchip: Add rockchip SPDIF transceiver driver")
