afd306cf79 nl80211: Remove send_and_recv_msgs()
This helper is of no real use anymore, so get rid of it. This completes
send_and_recv*() cleanup. What remains is the most generic
send_and_recv() and two wrappers for it to cover the most common simpler
cases.

ab506d7772 nl80211: Add send_and_recv_cmd() helper
This is a variant for the most common case of send_and_recv() needs:
send a command without needing a special response handling. In addition,
move the helper functions into driver_nl80211.h since these are now
simple wrappers for the more flexible send_and_recv().

da0d51fee7 nl80211: Use socket cb instead of global->nl_cb in send_and_recv()
This is a step towards cleaning up all the workarounds that have showed
up over the years and made the design difficult to understand. This
removes use of the separate registration of process_bss_event() as
NL_CB_VALID for the individual commands since the use of the appropriate
cb (i.e., the one from nl80211_init_bss() in these cases) will already
point to the correct handler.

This is a workaround for some race conditions where the hardcoded use of

2ab56694f6 Split ap_sta_set_authorized() into two steps
This function is both updating the hostapd-internal sta->flags value and
sending out the AP-STA-CONNECTED control interface message. When
authorizing a STA, the call to this function is followed by a driver
command to update the flags of the STA entry in the driver. That has a
race condition at least for UML time-travel since the AP-STA-CONNECTED
event is used as a message to wait for before running a connectivity
test or some other operation that depends on the data connection being
in working condition.

Split the function into two steps so that the driver STA entry update
can be done between those two steps for the cases where it matters for
the race condition. In other words, send the AP-STA-CONNECTED message
only after having authorized the STA in the driver.

For wpa_supplicant based SAE/OWE connection, the wpa_supplicant state
machine is aware of the PMKID created for a connection and this gets
removed when "REMOVE_NETWORK all" is called. However, when SAE/OWE
offload is enabled, wpa_supplicant is not aware of the PMKID generated
by the driver/firmware. So add PMKSA del indication to the driver from
remove_network context so that the driver can free PMKs associated with
