usb-uhci: stop queue filling when we find a in-flight td
Not only QHs can form rings, but TDs too. With the new
queuing/pipelining support we are following TD chains and
can actually walk in circles. An assert() prevents us from
entering an endless loop then.
Fix is easy: Just stop queuing when we figure the TD we are
about to queue up is in flight already.
