mlx4: add a new xmit_more counter
ethtool -S reports a new counter, tracking number of time doorbell
was not triggered, because skb->xmit_more was set.
$ ethtool -S eth0 | egrep "tx_packet|xmit_more"
tx_packets: 2413288400
xmit_more: 666121277
I merged the tso_packet false sharing avoidance in this patch as well.
