Yeah, we should, I agree. I'm not happy with this patch. I'm having a
really hard time unravelling wpas_p2p_group_delete() though, and we put
wpas_notify_p2p_group_removed() before wpa_supplicant_ap_deinit()
because I couldn't understand the NOT_P2P_GROUP_INTERFACE case etc.

So I think the solution is to somehow put
wpas_notify_p2p_group_removed() after wpa_supplicant_ap_deinit() in that
function, but I'm not exactly sure what the NOT_P2P_GROUP_INTERFACE
means for this.
