wpa_bss_in_use() used to determine that a BSS with BSSID of
00:00:00:00:00:00 is in use in almost every case since either
wpa_s->bssid or wpa_s->pending_bssid was likely to be cleared. This
could result in a corner case of a BSS entry remaining in the BSS table
indefinitely if one was added there with a (likely bogus) address of
00:00:00:00:00:00. Fix this by ignore wpa_s->bssid and
wpa_s->pending_bssid if the BSSID in the BSS table entry is
00:00:00:00:00:00.
In theory, that address is a valid BSSID, but it is unlikely to be used
in any production AP, so the potential expiration of a BSS entry with
that address during a connection attempt would not be a concern
(especially when a new scan would be enough to recover from that).

It was possible for the current network profile to be deleted when
merging duplicated WPS credentials. However, this did not clear
wpa_s->current_ssid and it was possible for something else to end up
dereferencing that pointer to now freed memory. This could be hit, e.g.,
with ap_wps_mixed_cred. Fix this by clearing current_ssid also in this
code path similarly to other cases of network block getting removed.

The mesh group addition was designed to use wpa_s->connect_without_scan
to skip a scan. That path was skipped if wpa_supplicant_fast_associate()
allowed previous scan results to be used. This could result in undesired

using wpa_supplicant_fast_associate() when wpa_s->connect_without_scan

It was possible for auth/assoc timeout/failure event from the driver to

It is possible for scan result processing or BSS entry removal to occur
while there is a pending connect or sme-connect radio work with a
previously selected BSS entry. The BSS pointer was previously verified
to be valid, i.e., still point to a BSS entry, at the time the actual
connection operation is started. However, that BSS entry could have
changed to point to another BSS if the old BSS entry was either removed
or reallocated and a new BSS entry was added at the same location in
memory. This could result in the connection attempt failing to configure
parameters properly due to different BSS information (e.g., different
BSSID).
Fix this by updated the pending connect radio work data on BSS entry
updates similarly to how the last_scan_res array was updated. If the
selected BSS entry is removed, this will still result in a failed
connection, but reallocated BSS entry is now followed properly and used
when the connection work starts.
