After the interrupt queueing was added, I don't think the old way of
resetting interrupts will work anymore.  This patch changes it to simply
do a full unlink and resubmission automatically.  Note that since
usb_hcd_giveback_urb() is never called for a resubmitting interrupt URB,
that means whatever gets released in usb_hcd_giveback_urb() won't get
released for that URB.  The only way to work around that is call
usb_hcd_giveback_urb after the user unlinks in their completion handler,
which will call the completion handler again with -ECONNRESET
status...which wouldn't be all that bad, but the drivers have to expect
it.

Hopefully the interrupt resubmission will go away soon...
