[PATCH] [media] cx88: Use common error handling code in get_key_pvr2000()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Mon, 25 Sep 2017 21:03:57 +0200

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.
