tests: Clear cfg80211 BSS table at the end of scan_hidden

It was possible for the hidden SSID entry to leak into following test
cases and result in failures, e.g., in this sequence:

scan_hidden
scan_reqs_with_non_scan_radio_work
radius_auth_unreachable
wep_open_auth

BSS <BSSID> picked incorrect BSS entry within wpa_supplicant due to the
old zero-length SSID showing up from the earlier hidden SSID case.
