[PATCH] net: rtnetlink: remove redundant assignment to variable err

[Colin King]

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

The variable err is being initializeed with a value that is never read
and it is being updated later with a new value. The initialization
is redundant and can be removed.
