net80211: proper ssid length check in setmlme_assoc_adhoc()

A user supplied SSID length is used without proper checks in
setmlme_assoc_adhoc() which can lead to copies beyond the end
of the user supplied buffer.
The ssid is a fixed size array for the ioctl and the argument
to setmlme_assoc_adhoc().
In addition to an ssid_len check of 0 also error in case the
ssid_len is larger than the size of the ssid array to prevent
problems.
