USB: ch9: add "USB_" prefix in front of TEST defines

For some reason, the TEST_ defines in the usb/ch9.h files did not have
the USB_ prefix on it, making it a bit confusing when reading the file,
as well as not the nicest thing to do in a uapi file.

So fix that up and add the USB_ prefix on to them, and fix up all
in-kernel usages. This included deleting the duplicate copy in the
net2272.h file.
