xhci: Don't warn on empty ring for suspended devices.
commit a83d6755814e4614ba77e15d82796af0f695c6b8 upstream.
When a device attached to the roothub is suspended, the endpoint rings
are stopped. The host may generate a completion event with the
completion code set to 'Stopped' or 'Stopped Invalid' when the ring is
halted. The current xHCI code prints a warning in that case, which can
be really annoying if the USB device is coming into and out of suspend.
Remove the unnecessary warning.
