From: Sven Eckelmann <s...@narfation.org>
The commit 9799c50372b2 ("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.
