You cannot build against the backports modules with the batman-adv Makefile.
This is only for systems which don't replace cfg80211 with an incompatible
version. But you should have a look at the OpenWrt compile rules (especially
NOSTDINC_FLAGS [1]). It basically uses its own compat-hack header and uses
the rest from the backports compat layer + the new cfg80211 headers.

Most important here is that you don't compile against cfg80211.h of your
kernel when your backports stuff uses complete different struct definitions
(this is most likely what causes the crash on your system).

Kind regards,
	Sven
