tests: Clear scan cache at the end of ap_wps_per_station_psk_failure

Browse Source 
It was possible for ap_wps_per_station_psk_failure to leave behind scan
entries with active PBC mode if cfg80211 BSS table. This could result in
a following test case failing due PBC overlap. Fix this by clearing the
cfg80211 BSS table explicitly.

This was found with the following test case sequence:
ap_wps_per_station_psk_failure autogo_pbc
