tests: wpa_supplicant AP mode - unexpected P2P IE in Association Request

This verifies that there is no NULL pointer dereference when the AP code
processes Probe Request and (Re)Association Request frames with a P2P IE
in case P2P support is explicitly disabled on the AP mode interface.
This is a regression test case for the fixes in the previous commit.
