netdev-dpdk: Add mempool count in cmd get-mempool-info.

Browse Source 
The rte_mempool_avail_count() and rte_mempool_in_use_count() DPDK API
can tell us the usage of the mempool.  It could be helpful for debug
on any memleak in the mempool.

Add a line in the cmd's output:
     count: avail (118988), in use (12084)
