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.
