fteeprom-{erase,prog}: detach logic: change to detach by default
As it turns out, detaching all ttyUSB interfaces of a multichannel device
does not require outside knowledge of how many channels there are, as in
our previous -d option design that is being removed here - instead we can
read the bNumInterfaces constant from the USB device's config descriptor
and thus know how many interfaces there are in total. Based on this
discovery, change the design of fteeprom-{erase,prog} as follows:
* remove -d option;
* flip the default to where we detach all interfaces by default;
* add -n option to NOT detach any interfaces.
