This is usually caused by a driver (in this case mac80211) implementing
ndo_set_features, but I never accepted that patch as far as I remember,
it's pending in patchwork. I don't see that in your tree either, so
that's very puzzling.
Clearly it's trying to turn off NETIF_F_GSO, as it should since the
drivers both don't advertise NETIF_F_SG right now.
The code you're looking at is in __netdev_update_features(), but I
can't explain how it would get into this message if ndo_set_features is
NULL. Perhaps you should recompile the kernel from scratch.
