[PATCH] [media] spca500: Use common error handling code in spca500_synch310()

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

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 22 Sep 2017 18:45:07 +0200

Adjust 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.
