batman-adv: make hard_iface->mesh_iface immutable

Browse source

With the hard_iface now being created for a specific mesh_iface, it is
beneficial not to set mesh_iface to NULL when the interface is disabled,
but instead keeping it immutable after the initial setup of the
hard_iface. By also holding the reference to the mesh_iface until the
hard_iface is released, hard_ifaces iterated over under RCU will always
point to a valid mesh_iface.
