Subject: [PATCH] seg6_iptunnel: Remove redundant initialization of variable err

From: Colin Ian King <colin.king@...onical.com>

The variable err is being initialized with a value that is never read, it
is being updated later on. The assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
