ospfd: allow interfaces to come up in rare situation

ospfd: allow interfaces to come up in rare situation

On startup of both zebra and ospfd.  If ospfd has not
received a valid router-id *but* has received interface
data, interfaces will not be turned on in the state
machine.  When ospf finally receives a valid router-id
it would never actually kick the state machine into
action for those interfaces it has been configured for.

Modify ospf on router id changes, *if* the old
router id was INADDR_ANY *and* the interface is
operative *and* the oi->state is ISM_Down, give
it the old kick in the patooeys
