ASoC: cs4271: Fix resource leak in cs4271_soc_resume()

Smatch detects this resource leak:

sound/soc/codecs/cs4271.c:548 cs4271_soc_resume() warn:
 'cs4271->clk' from clk_prepare_enable() not released on lines: 540,546.

Instead of direct returns, unprepare the clock and disable regulators on
the error paths.

Fixes: cf6bf51 ("ASoC: cs4271: Add support for the external mclk")
Fixes: 9a397f4 ("ASoC: cs4271: add regulator consumer support")
