[PATCH net] sunvnet: set queue mapping when doing packet copies

[David L Stevens <david.stevens@oracle.com>]

[resending this since it never appeared on netdev yesterday]

This patch fixes a bug where vnet_skb_shape() didn't set the already-selected
 queue mapping when a packet copy was required. This results in using the
 wrong queue index for stops/starts, hung tx queues and watchdog timeouts
 under heavy load.
