[PATCH] misc: bh1770glc: Use common error handling code in bh1770_power_state_store()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 27 Oct 2017 18:00:31 +0200

Adjust jump targets so that a bit of exception handling can be better
reused in an if branch of this function.

This issue was detected by using the Coccinelle software.
