nl80211: Fix send_mlme to use monitor interface only for AP interface

Browse source 
Use monitor interface to send_mlme only when the interface is configured
in AP mode. In multiple interface setup, one interface can be configured
in AP mode using monitor interface and another interface in station
mode. The station interface may also require sending the management
frames without using monitor interface, e.g., support external SAE
authentication to send Authentication frames without monitor interface.
This change allows sending management frames to the driver for a station
interface where the AP interface uses monitor interface.

Additionally, the monitor interface is only valid for AP mode
(nl80211_create_monitor_interface() is called in nl80211_setup_ap) so
interface type check ensures to use monitor interface only when required
by the specific interface.
