i40e: Reorder logic for coalescing RS bits
This patch reorders the logic at the end of i40e_tx_map to address the
fact that the logic was rather convoluted and much larger than it needed
to be.
In order to try and coalesce the code paths I have updated some of the
comments and repurposed some of the variables in order to reduce
unnecessary overhead.
This patch does the following:
1. Quit tracking skb->xmit_more with a flag, just max out packet_stride
2. Drop tail_bump and do_rs and instead just use desc_count and td_cmd
3. Pull comments from ixgbe that make need for wmb() more explicit.
