Looks good to me. Even though I could not repeat the conditions to cause 
one of these errors, the additons make sense.

In my testing, I did add in several rte_mempool_avail_count() checks to 
see if there were leakages, and all the mempool counts were
stable, but that was due to the fixes in the patch set from Lukasz : 
http://patches.dpdk.org/project/dpdk/list/?series=12442

However, if there are situations where packets are not returned from 
workers, this should clean them up nicely before returning.
