Soon BSS blacklisting will be added, and in order to properly decide if a BSS should be blacklisted we need the status code on a failed connection. This change stores the status code when there is a failure in netdev and adds a getter to retrieve later. In many cases we have the actual status code from the AP, but in some corner cases its not obtainable (e.g. an error sending an NL80211 command) in which case we just default to MMPDU_REASON_CODE_UNSPECIFIED. Rather than continue with the pattern of setting netdev->result and now netdev->last_status_code, the netdev_connect_failed function was redefined so its no longer used as both a NL80211 callback and called directly. Instead a new function was added, netdev_disconnect_cb which just calls netdev_connect_failed. netdev_disconnect_cb should not be used for all the NL80211 disconnect commands. Now netdev_connect_failed takes both a result and status code which it sets in the netdev object. In the case where we were using netdev_connect_failed as a callback we still need to set the result and last_status_code but at least this is better than having to set those in all cases.
