When multiple measurement requests are received in a single beacon
report request, multiple iterative scans are triggered for each
request for the frequency list provided in the request. This results
in free of rrm context global frequency list by the second
request rrm scan in the iter measurement timer start failure path
and was accessed by the scan done callback of the 1st measurement
request.
Add null check for rrm context frequency list and also if the
timer is already running, send measurement done indication for
that request.
