H3C SR6604 session 优

由于业务流量不断增大，导致 6604的内存占用不断升高，为避免由路由器内存占用过大影响设备整体性能，对路由器的会话参数做了以下调整。

调整前：

[XXXX6604]dis session aging-time  Protocol                 Aging-time(s)  syn                      30  tcp-est                  3600  fin                      30  udp-open                 30  udp-ready                60  icmp-open                60  icmp-closed              30  rawip-open               30  rawip-ready              60  accelerate               10
