[PATCH] UHCI: Remove non-iso TDs as they are used
This patch (as680) frees non-isochronous TDs as they are used, rather
than all at once when an URB is complete. Although not a terribly
important change in itself, it opens the door to a later enhancement
that will reduce storage requirements by allocating only a limited
number of TDs at any time for each endpoint queue.
