batman-adv: Fix double-hold of meshif when getting enabled
It was originally meant to replace the dev_hold with netdev_hold. But this
was missed in batadv_hardif_enable_interface(). As result, there was an
imbalance and a hang when trying to remove the mesh-interface with
(previously) active hard-interfaces:
unregister_netdevice: waiting for batadv0 to become free. Usage count = 3
Fixes: 00b35530811f ("batman-adv: adopt netdev_hold() / netdev_put()")
