PBC overlap detection searches for another BSS with active PBC in the
BSS table. However, when a separate P2P interface is used, scan results
without P2P IE are not saved in the BSS table, so non-P2P BSS's with
active PBC will not be detected.
Fix this by iterating only the WPS AP array instead of the BSS table.
This is also more efficient since only WPS APs may have active PBC. This
also fixes hwsim test "grpform_pbc_overlap" when a dedicated P2P Device
is used.

The test sequence "scan_and_bss_entry_removed ap_wps_ap_scan_2" resulted
in failure due to an old BSS entry remaining from the first test case to
the second and the WPS_PBC operation on a forced BSSID ending up picking
the incorrect BSS entry. Make this more robust by clearing the scan
results from cfg80211.

Both of these test cases were leaving out BSS entries with active PBC
mode at the end of the test. This could result in the next text case
failing, e.g., in "ap_wps_pbc_overlap_2ap grpform_ext_listen" and
"ap_wps_pbc_overlap_2sta grpform_ext_listen" sequences. Fix this by
flushing the scan results more carefully at the end of the PBC overlap
test cases.

If a seeker constantly hears the Probe Response frames from a P2P Client
and then from the GO, but handles them in the opposite order (due to
