Looks like one of the chains off xfrm_policy_list[] might have gone

This patch fixes it. When a policy with a priority lower than an
existing policy is inserted, it loops forever on the existing policy.

Subject: ipsec hang


Hi,
today I tried to configure ipsec on my linux workstation (with openswan) and 
it hanged just after the init had run /etc/rc.d/init.d/ipsec start. 
It was on linux-2.6.10-rc1-bk20, so I upgraded to 2.6.10-rc2-mm3 but it didn't 
make any difference. 

The alt-sysrq-p shows the following call trace:
xfrm_policy_insert
xfrm_netlink_rcv
netlink_data_ready
netlink_sendmsg
sock_aio_write
do_sync_write
sock_map_fd
sys_select
vfs_write
