sctp: drop unnecessary __packed from some stream reconf structures
commit 85c727b59483 ("sctp: drop __packed from almost all SCTP structures") has removed __packed from almost all SCTP structures. But there still are three structures where it should be dropped. This patch is to remove it from some stream reconf structures. Signed-off-by: Xin Long <lucien.xin@gmail.com> Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.
