Mathias Nyman 44f2ed29e1 xhci: Fix incorrect tracking of free space on transfer rings ... commit fe82f16aafdaf8002281d3b9524291d4a4a28460 upstream. This incorrect tracking caused unnecessary ring expansion in some usecases which over days of use consume a lot of memory. xhci driver tries to keep track of free transfer blocks (TRBs) on the ring buffer, but failed to add back some cancelled transfers that were turned into no-op operations instead of just moving past them. This can happen if there are several queued pending transfers which then are cancelled in reverse order. Solve this by counting the numer of steps we move the dequeue pointer once we complete a transfer, and add it to the number of free trbs instead of just adding the trb number of the current transfer. This way we ensure we count the no-op trbs on the way as well.
