So can you put a few printks into the function to see where it dereferences
a NULL pointer? (or use gdb to lookup the offset).

u8 key_idx = info->control.hw_key->hw_key_idx;

info->control.hw_key is NULL.

Is a NULL pointer supposed to tell "do not encrypt", or is this a mac80211 bug?

It's probably a bug.
