usb_disk: Cancel queued transfers when clearing HALTs.

Browse Source 
XHCI, at least, has "sticky" HALT states which must be cleared at
the controller level. Invoking cancel_queued_transfers takes care
of this.

This fixes USB disks spontaneously unmounting whenever stalls occur.
However, trying to read anything from the mounted partition results
in "Bad file descriptor", probably due to media-status error propagation.
