Jason Wang e430451613 vhost-net: flush batched before enabling notifications

Commit 8c2e6b26ff ("vhost/net: Defer TX queue re-enable until after
sendmsg") tries to defer the notification enabling by moving the logic
out of the loop after the vhost_tx_batch() when nothing new is spotted.
This caused unexpected side effects as the new logic is reused for
several other error conditions.

A previous patch reverted 8c2e6b26ff. Now, bring the performance
back up by flushing batched buffers before enabling notifications.
