Slight dead-loop problem in the ohci code,
just need to swap two adjacent lines.

It didn't fix the data toggle issue I've had in avrdude-5.10
(but there's a work-around in 5.10nb1).
With a AVRISP mkII plugged into a nforce4 ohci, the data toggle
issue on the second and every-other-thereafter operations remains.

Oddly, it appears that this USB 1.1 device doesn't work via
a USB 2.0 hub, so I can't really claim regression there.
(I've found accounts of a similar issue, so, yeah ...)

Lastly, it doesn't fix 37884, but I didn't really expect it to.
