Fix "RTNETLINK answers: No such process" when starting redundant router

The issue happened quite rare, but indeed can show.

And when the issue happen, the status of redundant router would be "Status:
FAULT".

It's due to ipassoc.sh wasn't executed before the system bring eth2 up and go to
master mode, then eth2 wasn't configured correctly. Then "ip route add default
xx" can't complete.

This commit should fixes the issue.
