Subject: [PATCH 2/2][next] ASoC: rockchip: i2s-tdm: Fix error handling on i2s_tdm_prepare_enable_mclk failure

From: Colin Ian King <colin.king@...onical.com>

In the case where the call to i2s_tdm_prepare_enable_mclk fails the
function returns before the error handling goto is executed. Fix this
by removing the return do perform the intended error handling exit.

Fixes: 081068fd6414 ("ASoC: rockchip: add support for i2s-tdm controller")
Addresses-Coverity: ("Structurally dead code")
