[PATCH v6 3/4] ASoC: Intel: cht_bsw_rt5672: Fix MCLK leak on platform_clock_control error

[aravindanilraj0702]

From: Aravind Anilraj <aravindanilraj0702@xxxxxxxxx>

If snd_soc_dai_set_pll() or snd_soc_dai_set_sysclk() fail inside the
EVENT_ON path, the function returns without calling
clk_disable_unprepare() on ctx->mclk, which was already enabled earlier
in the same code path. Add the missing clk_disable_unprepare() calls
before returning the error.
