When SAE roaming happens, the preauth event BSSID is used to
trigger external authentication to userspace and frame exchange
also happens with this BSSID. But while caching the info
corresponding to this frames, the current connected AP bssid is

Use correct BSSID to fetch the cached SAE authentication frames
for MLO SAE roaming. Enhance the error logs in some cases.

When wifi is turned off, if the connectivity logging queue is
not empty, the wlan logging thread tries to dequeue the record
and send the logging event to the userspace. While performing
dequeue operation, the records from queue are copied to temporary
buffer before read pointer is incremented. There could be a
condition where this buffer is allocated in ini domain after stop
modules is done and freed in active domain if the wlan_logging
thread is preempted during stop modules.
So to avoid this domain mismatch, start the queue only if
start_modules is done and stop the queue after stop modules
to avoid dequeue being done during/after stop modules.
