This patch fixes a few debugging print statements whose arguments fell
out of sync over time with changes being made to the active code base.

Turning EHCI_DEBUG on gave me compile errors. This is my best guess
as to what the DPRINTF arguments *should* be, hope I guessed right :)

This patch works against both master and the q35 branch, BTW.

I'll reply to your email again with the debug output, figured I'd get
this out of the way first...

Thanks,
  Gabriel

In that case I'll let Gerd confirm whether or not the guesses are
correct.

Gerd: can you review and take this through the USB tree?

Thanks,
Stefan
