ehci: Set int flag on a short input packet
According to 4.15.1.2 an interrupt must be raised when a short packet is received. If we don't do this it may take a significant time for the guest to notice a short trasnfer has completed, since only the last td will have its IOC flag set, and a short transfer may complete in an earlier packet.
