"op 21" is the request to associate.  The error most likely indicates
the kernel had no information about the ap at the point where the ioctl
was issued.  Adding -d to the command line would provide useful info.

ap_scan has no effect on freebsd if I recall; it's really intended for
linux and other os's where a variety of drivers hook up to
wpa_supplicant.  On freebsd all drivers (except for ndis) go through
net80211 and scanning is handled uniformly.
