David Brownell 79592b722e USB: ehci completes high speed ISO URBs sooner 
This has some bugfixes for the EHCI driver's ISO transfer scanning
logic.  It was leaving ITDs and SITDs on the schedule too long, for
a few different reasons, which caused trouble.

  (a)	Look at all microframes for high speed transfers, not just
	the ones we expect to have finished.  This way transfers
	ending mid-frame will complete without needing another IRQ.
	This also minimizes bogus scheduling underruns (e.g. EL2NSYNC).

  (b)	When we encounter an ISO transfer (either speed, but this
	hits mostly at full speed) that's not yet been completed,
	immediately stop scanning; we've caught up to the hardware,
	no matter what other indications might say.

  (c)	Always clean up ITDs (for high speed transfers) when the HC
	is no longer running.

I'm not sure whether the last one has been observed before, but both
the others have been reported with "real world" audio and video code.
