WifiManagerTest: Fetch scan results only on scan success

When wifi location scans are off, the scan is expected to fail. But,
WifiManager.getScanResults() could still return results from the last
scan. This was causing the test to fail because it was relying on
|mScanResults| being null to detect scan failure.

Also, changed the scan done internal state name in the test to more accurately
reflect that scan has been completed (could be success or failure).

Bug: 77601152
Test: Ran `atest android.net.wifi.cts.WifiManagerTest#
testWifiManagerScanWhenWifiOffLocationTurnedOn` with location turned on,
but wifi scans turned off.
