[PATCH] ASoC: bells: Use common error handling code in bells_set_bias_level_post()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 19 Nov 2017 15:00:22 +0100

* Add a jump target so that a specific error message is stored only once
  at the end of this function implementation.

* Replace two calls of the macro "pr_err" by goto statements.

This issue was detected by using the Coccinelle software.
