netdev: remove callback/userdata/timeout from FT-over-DS action

Browse Source 
Since netdev maintains the list of FT over DS info structs there is not
any need for station to get callbacks when the initial action frame
is received, or not. This removes the need for the callback handler,
user data, and response timeout.
