* [B.A.T.M.A.N.] [PATCH v2] batman-adv: B.A.T.M.A.N. V - implement hard-iface init function

Some fields in the hard-interface data structure are specific to the
B.A.T.M.A.N. V protocol and have to be initialized only when such
protocol is compiled in.
Instead of having a #ifdef block in the middle of the hard-interface.c
code it is better to have an algorithm private function that hides the
precompiler logic in its own header file (like other functions).

Fixes: ffd2f27908e5 ("batman-adv: Only init ELP tweaking options when BATMAN_V is enabled")
Signed-off-by: Antonio Quartulli <a@unstable.cc>

Changes from v1:
- move bat_algo.h include line to the right location
