After SKB is queued into tx_queue, it will be freed if request_gop is NULL.
However, no dequeue action is called in this situation, it is likely that
tx_queue constains freed SKB. This patch should fix this issue, and it is
based on 3.5.0-rc4+.

This issue is found through code inspection, no bug is seen with it currently.
I run netperf test for several hours, and no network regression was found.

I lack the expertiece necessary to properly review this, so I really
need a Xen expert to look this over.

Sorry, I put it to one side waiting for the repost to netdev and then
forgot about it...

Yes, this change looks good to me:
