Subject: [PATCH] xen-netback: remove redundant assignment to err

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

The variable err is assigned with the value -ENOMEM that is never
read and it is re-assigned a new value later on.  The assignment is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
