ASoC: Intel: bytcr_rt5651: Fix MCLK leak on platform_clock_control error

If byt_rt5651_prepare_and_enable_pll1() fails, the function returns
without calling clk_disable_unprepare() on priv->mclk, which was
already enabled earlier in the same code path. Add the missing
cleanup call to prevent the clock from leaking.
