On ethdev there is an API to configure VLAN offloads after the port
was started and without reconfiguration of the port or queues.

In the current design of the application, when the Rx offloads are
changed (through "port config all" CLI command) the port configuration
is overwritten, therefore the configuration made for the VLAN is lost.

This patch is to address the issue by a configuration of each port Rx
offloads separately instead of using the global Rx config.

Fixes: 6dbb2b336586 ("app/testpmd: convert to new Ethdev Rx offloads API")
