staging: r8188eu: remove remaining DBG_88E call from include/usb_ops.h

Remove the one remaining DBG_88E call from include/usb_ops.h. After
some thought, it makes more sense to just entirely strip all of these
calls, so that debugging code in the driver can be more consistent and
useful going forwards.
