batman-adv: v: stop OGMv2 on disabled interface

In the Linux kernel, the following vulnerability has been resolved:

batman-adv: v: stop OGMv2 on disabled interface

When a batadv_hard_iface is disabled, its mesh_iface pointer is set to
NULL. However, batadv_v_ogm_send_meshif() may still dispatch OGMs via
batadv_v_ogm_queue_on_if() for interfaces that have since lost their
mesh_iface association. This results in a NULL pointer dereference when
batadv_v_ogm_queue_on_if() unconditionally calls netdev_priv() on the
now NULL hard_iface->mesh_iface to retrieve the batadv_priv.

It is necessary to ensure that the batadv_v_ogm_queue_on_if() checks that
it is using the same mesh_iface for which batadv_v_ogm_send_meshif() was
called.
