[2/4] batman-adv: compat: fix warning in hard-interface.c for < 4.0
Commit Message
This fixes the following warning:
hard-interface.c:104:39: warning: incorrect type in return expression (different base types)
hard-interface.c:104:39: expected struct net *
hard-interface.c:104:39: got bool
Which allows compiling with -Werror again on kernels < 4.0.
Fixes: bea804dbde21 ("batman-adv: Handle parent interfaces in a different netns")
