Subject: [PATCH net-next 06/12] ice: Use common error handling code in two functions

From: Markus Elfring <elfring@...rs.sourceforge.net>

Add jump targets so that a bit of exception handling can be better reused
at the end of two function implementations.

This issue was detected by using the Coccinelle software.
