wlan: Use unique logging for driver commands

There are two different mechanisms by which driver commands may be sent,
either by Wireless Extensions private ioctls or by regualr device
private ioctls.  Currently when processing a driver command the log
message does not indicate via which mechanism the command was received.
Since knowing this information aids in debugging, modify the log
messages so that they indicated the function that is handling the
message.
