This patch implements various cleanups and fixes aimed to
simplify adding AP_VLAN support to qtnfmac driver:

- Remove unused flag field from qlink_intf_info
- Add interface type to qlink_cmd_change_sta
- Modify qtnf_cmd_send_change_sta: add interface type to command
- Fix handling of iftype mask reported by firmware:
  Firmware sends supported interface type rather than mask. As a result,
  types field of ieee80211_iface_limit structure may end up having
  multiple iftype bits set. This leads to WARN_ON from
  wiphy_verify_combinations.

Again multiple changes in one patch.

Ok, I will split this patch into more reasonable chunks in v2.
