[dpdk-dev] [PATCH v3 16/29] net/pfe: release port upon close

From: Sachin Saxena <sachin.saxena at oss.nxp.com>
With removal of old close behavior, the private
port resources must be released in the .dev_close callback.
Freeing of port private resources is moved from
the ".remove(device)" to the ".dev_close(port)" operation
