Change beacon request fields to appropriate values

Browse source 
This changes the op_class, channel, and SSID fields used to send a
beacon request.  Op_class and channel were set from the UCI config file,
but they are dependent on the band being used--they define the frequency
used.  The values can be taken from the AP's own neighbor report.

The SSID was set with a blank string, which would return beacons from
any SSID.  Since we only care about our own SSID, there's no need to
waste resorces with reports from other SSIDs.
