USB: EHCI: fix ITD list order
commit 92bc3648e6027384479852b770a542722fadee7c upstream.
When isochronous URBs are shorter than one frame and when more than one
ITD in a frame has been completed before the interrupt can be handled,
scan_periodic() completes the URBs in the order in which they are found
in the descriptor list. Therefore, the descriptor list must contain the
ITDs in the correct order, i.e., a new ITD must be linked in after any
previous ITDs of the same endpoint.
This should fix garbled capture data in the USB audio drivers.
