[PATCH 2/7] Babel: Immediately send a hello on interface reconfigure.

[Toke Høiland-Jørgensen]

An interface reconfiguration may change the hello interval. Section
3.4.1 of the RFC specifies that either the change shouldn't be applied
until the next hello is due, or an additional hello should be sent
immediately. This does the latter.
