Jouni Malinen 4ef7053119 tests: Make GAS test cases more robust 
Scan explicitly for the specific AP to work around issues where under
heavy CPU load, the single active scan round may miss the delayed Probe
Response from the AP. In addition, verify that ANQP_GET commands succeed
to make error cases clearer in the log.
