correct USB context.

Hi,
How are people/users of libusb supposed to disable these messages
after this? The only thing stopping them was the debug level in the
context, I guess, because DPRINTF is always compiled to this and the
users of DPRINTF are just invoking it all willy-nilly.
Feel free to submit a patch. Maybe you need to make a new option for
user-space like WITH_USB_DEBUG ....
