autoscan: Disable when we move above WPA_SCANNING state

In case of drivers that don't use wpa_supplicant as SME, autoscan
feature was never disabled.

SAE: Use open authentication to reassociate for PMKSA caching

For reassociation with the same AP wpa_supplicant attempts to use cached
PMKSA. For this purpose PMKID is passed in RSNE in (Re)Association
Request frame. In the case of SAE AP, open authentication shall be used
during reassociation. Otherwise cached PMKID becomes invalid after full
SAE authentication.

The previous implementation correctly handles SME-in-wpa_supplicant
cases. However SME-in-driver cases, complete SAE authentication is
performed. As a result, first reassociation attempt fails.

Fix SME-in-driver behavior by reseting authentication algorithm to
WPA_AUTH_ALG_OPEN when reassociating with SAE AP with an existing PMKSA
cache entry.

Fix FILS ERP association event with 4-way HS offload drivers

When FILS authentication is used with ERP, no EAPOL frames are expected
after association. However, for drivers that set the
WPA_DRIVER_FLAGS_4WAY_HANDSHAKE_8021X capability flag, the EAP state
machine was not configured correctly and was waiting for EAPOL frames,
which leads to disconnection.

Fix this by reordering the if branches to set the EAPOL/EAP state
machines to success when FILS authentication was already completed.

nl80211: Handle NL80211_CMD_PROBE_CLIENT command response

When processing the NL80211_CMD_PROBE_CLIENT command response, the
nl80211 layer in the kernel sends a response containing the cookie
associated with the client probe request. This response was not handled
by driver_nl80211.c when sending the command, and it was mistakenly
handled as an asynchronous event. This incorrect event did not include
the MAC/ACK attributes, so it was ignored in practice, but nevertheless,
the command response should not be processed as an event.

Fix this by reading the response as part of the sending the command
flow.

nl80211: More detailed PROBE_CLIENT debug print

Include the MAC address of the peer, knowledge of whether the poll was
ACKed, and cookie into the debug message to make this more useful.

Do not clear FT IEs twice in sme_deinit()

Remove FT IEs clearing from sme_deinit() as it is done twice. The
sme_clear_on_disassoc() call to sme_update_ft_ies() takes care of this.

Stop SA Query on disconnection

SA Query wasn't stopped after disconnection, which could potentially
result in an unexpected SA timeout firing later when already connected
to another AP. Fix that by stopping SA Query when an association is
terminated.
