Subject: [PATCH] ipv6: remove redundant assignment to variable err

From: Colin Ian King <[email protected]>

The variable err is being initialized 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. Also re-order variable declarations in reverse
Christmas tree ordering.
