usb: xhci_suspend is not stopping the root hub timer for the shared HCD
V2 - Restart polling (which will restart the timer) for the shared HCD in xhci_resume(). xhci_suspend() will stop the primary HCD's root hub timer, but leaves the shared HCD's timer running. This change adds stopping of the shared HCD timer.
