batadv_tt_prepare_tvlv_local_data can fail to allocate the memory for the

The commit 9799c50372 ("batman-adv: fix splat on disabling an interface")
fixed a warning but at the same time broke the rtnl function add_slave for
devices which were temporarily removed.
batadv_softif_slave_add requires soft_iface of and hard_iface to be NULL
before it is allowed to be enslaved. But this resetting of soft_iface to
NULL in batadv_hardif_disable_interface was removed with the aforementioned
commit.

As long as there is still a reference for a hard interface held, there might
still be a forwarding packet relying on its attributes.
Therefore avoid setting hard_iface->soft_iface to NULL when disabling a hard
interface.
This fixes the following, potential splat:
batman_adv: bat0: Interface deactivated: eth1
batman_adv: bat0: Removing interface: eth1
cgroup: new mount options do not match the existing superblock, will be ignored
batman_adv: bat0: Interface deactivated: eth3

What happened here is, that there was still a forw_packet (here: a BATMAN IV
OGM) in the queue of eth3 with the forw_packet->if_incoming set to eth1 and the
forw_packet->if_outgoing set to eth3.
When eth3 is to be deactivated and removed, then this thread waits for the
forw_packet queued on eth3 to finish. Because eth1 was deactivated and removed
earlier and by that had forw_packet->if_incoming->soft_iface, set to NULL, the
splat when trying to send/flush the OGM on eth3 occures.

The files provided by batman-adv via debugfs are currently converted to
netlink. Tools which are not yet converted to use the netlink interface may
still rely on the old debugfs files. But systems which already upgraded
their tools can save some space by disabling this feature. The default
configuration of batman-adv on amd64 can reduce the size of the module by
around 11% when this feature is disabled.

Switch-like virtual interfaces like bridge or openvswitch don't destroy
itself when all their attached netdevices dissappear. Instead they only
remove the link to the unregistered device and keep working until they get
removed manually.
This has the benefit that all configurations for this interfaces are kept
and daemons reacting to rtnl events can just add new slave interfaces
without going through the complete configuration of the switch-like
netdevice.
Handling unregister events of client devices similar in batman-adv allows
users to drop their current workaround of dummy netdevices attached to
batman-adv soft-interfaces.
