xHCI: Cleanup isoc transfer ring when TD length mismatch found

commit cf840551a884360841bd3d3ce1ad0868ff0b759a upstream.

When a TD length mismatch is found during isoc TRB enqueue, it directly
returns -EINVAL. However, isoc transfer is partially enqueued at this time,
and the ring should be cleared.

This should be backported to kernels as old as 2.6.36, which contain the
commit 522989a27c7badb608155b1f1dea3487ed431f74 "xhci: Fix failed
enqueue in the middle of isoch TD."
