Yuan Wang 1907ce4bae examples/vhost: fix retry logic on Rx path 
drain_eth_rx() uses rte_vhost_avail_entries() to calculate
the available entries to determine if a retry is required.
However, this function only works with split rings, and
calculating packed rings will return the wrong value and cause
unnecessary retries resulting in a significant performance penalty.

This patch fix that by using the difference between tx/rx burst
as the retry condition.

Fixes: be800696c2 ("examples/vhost: use burst enqueue and dequeue from lib")
