[PATCH v2 3/3] Sony-laptop: Use common error handling code in sony_nc_setup_rfkill()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 1 Nov 2017 19:17:01 +0100

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.

This issue was detected by using the Coccinelle software.

Signed-off-by: Markus Elfring <elfr...@users.sourceforge.net>

v2:
This software refactoring was repeated after the error code handling was
adjusted for two function calls.
