sctp: reduce indent level in sctp_copy_local_addr_list
This patch is to reduce indent level by using continue when the addr is not allowed, and also drop end_copy by using break. Signed-off-by: Xin Long <lucien.xin@gmail.com> Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
