[PATCH -next] ASoC: tegra20-ac97: add missing clk_disable_unprepare() on error path

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei-zrsr2BFq86L20UzCJQGyNP8+0UxHXcjY@public.gmane.org>

Add the missing clk_disable_unprepare() before return from
tegra20_ac97_platform_probe() in the error handling case.

Mark, I did check that this patch doesn't conflict with any of the ASoC
changes I have in the Tegra tree, so there should be no issue when you
apply it. The same goes for the previous patch from Wei too, which fixes
some return values from this same function.
