[B.A.T.M.A.N.] [RFC] batman-adv: invoke ogm_schedule() only when the interface is activated

[Antonio Quartulli <antonio@meshcoding.com>]

From: Antonio Quartulli <ordex@autistici.org>

In the current implementation the first OGM is scheduled
when a new hard-interface is enabled, no matter if it is
active (thus ready for sending packets) or not.
The B.A.T.M.A.N. IV scheduling mechanism works in a way
that reschedules the task forever even if the interface is
not active and therefore everything works as expected.

Unfortunately this behaviour is not fine for other
algorithms which may expect the interface to be active
before scheduling the first OGM.

Therefore change this behaviour by scheduling the first OGM
on interface activation.
