Log:
SVN rev 189029 on 2009-02-25 11:18:18Z by rwatson
Correct a deadlock and a rtentry leak in rt_check():
- In the event that a gateway route has to be looked up, drop the lock
on 'rt' before reacquiring it 'rt0' in order to avoid deadlock.
- In the event the original route has evaporated or is no longer up
after the gateway route lookup, call RTFREE() on the gateway route
before retrying.
This is a potential errata candidate patch.
