usb: host: Replace empty define with do while
It's dangerous to use empty code define. Furthermore it lead to the following warning: "suggest braces around empty body in an « else » statement" So let's replace emptyness by "do {} while(0)" Furthermore, as suggested by Joe Perches, rename the macro to INCR.
