each scan request made via nwam_wlan_scan() in libnwam results in a detached
thread being created in nwamd that gets the object lock for the relevant ncu,
processes the scan request and releases the lock. We should probably limit scan
requests on the basis of the time of the last scan (stored in
link->nwamd_link_wifi_last_scan_time). If the interval between now and that
value is greater than WIRELESS_SCAN_REQUESTED_INTERVAL_MIN (10s say), no
additional scan is done.
We use detached threads to process connect requests also, but we can't drop
connect requests as they could in theory refer to different WLANs.
