[dpdk-stable] [PATCH] net/softnic: fix memory leak of meter policy

[dapengx.yu at intel.com]

From: Dapeng Yu <dapengx.yu at intel.com>

After the meter policies are created, they are not freed on device
close.

This patch fixes it.

Fixes: 5f0d54f372f0 ("ethdev: add pre-defined meter policy API")
