Subject: [PATCH] net/bonding: free mempool used in mode 6

[ upstream commit b9c0dea24beb4b893e88d93c1b52481003ff8999 ]

When creating bond device with mode6, dpdk will create
mempool for arp packets. If free the bond device and
create it with same name, there will be an error. Because
the mempool is not freed when destroying bond device.

Fixes: 06fe78b98ccd ("bond: add mode 6")
Fixes: ea0c20ea95fd ("apps: use helper to create mbuf pools")
