[PATCH 1/2]: wpa_gui-qt4: get bssid count before iterating through scan results

Use the new "BSS count" ctrl interface command to determine upper limit of
how many bssid's are expected to be in the scan results.

When iterating through scan results in a loop, break when the amount of results
processed is equal to the upper limit.
