[PATCH] USB: Let usbmon collect less garbage 

Alan Stern pointed out that (in 2.6 kernel) one successful submission results
in one callback, even for ISO-out transfers. Thus, the silly check can be
removed from usbmon. This reduces the amount of garbage printed in case
of ISO and Interrupt transfers.
