I tried to trace back where the problem is in the code but can not found anything strange, since the modules that I compiled from backports seems normal (though I get some warnings (unused variable and defined but not used like:
/backports-output/net/wireless/sysfs.c:78:1: warning: 'init_ieee80211_attrs' defined but not used [-Wunused-function]
/backports-output/drivers/net/wireless/ath/ath10k/ce.c:337:21: warning: unused variable 'ar_pci' [-Wunused-variable]
/backports-output/net/mac80211/chan.c:858:26: warning: unused variable 'local' [-Wunused-variable]

DO I have to activate cfg80211 and mac80211 when I built my old kernel 3.2.36 (so that the .config of the kernel is changed) or I can build them directly from backport? I just link them to my kernel by setting KLIB=... and KLIB_BUILD=...
