[PATCH 9/9] [media] tm6000: Use common error handling code in tm6000_prepare_isoc()

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

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 15 Sep 2017 08:02:33 +0200

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