[PATCH 8/9] [media] tm6000: Use common error handling code in tm6000_start_stream()

[SF Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 15 Sep 2017 07:47:41 +0200

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