[PATCH] PATCH ehci -- interrupt xfer requeue

The fix basically removes a bit-complement that shouldn't have
been there.  (Plus related simplification.)  That changed the PID,
so that (for one example) only the first hub plug/unplug event could
work.  So it's essential for anyone using high speed hubs.

I'm still not quite sure why this hasn't affected more testing, but
that's life ... :)
