If the last scans are recent (for now, less than ten seconds old), use
them instead of triggering a new scan when a BSS Transition Management
Request frame is received. As a fallback, allow a new scan to be

Switch the stop and sending DelTS to avoid sending data packets
for the session after the DelTS, which is otherwise possible.
This also helps the mac80211 implementation as it requires stopping the
traffic flow before sending the DelTS as it may modify the AC parameters
for the affected queue, and that may in turn affect management frames.

If p2p_stop_find is issued after the p2p_scan request is triggered to
the host driver, the obtained scan results are also considered to update

final pending scan.

With the radio work interface in place, station interface SCAN command
was not scheduled (i.e., it got continously delayed with "Delay station

operational. Fix this be delaying station mode scan only when a P2P
operation is in progress, but not in search state.

With the radio work interface, the actual request to start p2p_scan
operation is scheduled from a radio work and hence the initial return
value cannot provide the real result of the driver operation to trigger
a scan. Introduce a new notification API to indicate the scan trigger
status based on which the p2p_scan_running instance can be set using the
real return value from the driver operation.

In theory, wpas_p2p_disconnect_safely() could have dereferenced the
wpa_s == NULL argument, but in practice, it won't due to the
calling_wpa_s == wpa_s check and wpas_p2p_disconnect() accepting NULL.
Anyway, it is cleaner to add an explicit check for this. (CID 74492)

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.
