[IPV4]: Small style cleanup of the error path in rtm_to_ifaddr.
Remove error code assignment inside brackets on failure. The code looks better if the error is assigned before condition check. Also, the compiler treats this better. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
