ftdi: Report an error if no ftdi_vid_pid is specified

By default the list of VID/PID is empty so if ftdi_vid_pid is not called
then no matches are attempted. The only message is at -d3:

	Command 'init' failed with error code -100"

Check for this condition explicitly to make life easier for people
configuring adapters.
