examples/l3fwd-power: support virtio/vhost

Browse Source 
In l3fwd-power, there is default port configuration which requires
RSS and IPv4/UDP/TCP checksum. Once device does not support these,
the l3fwd-power will exit and report an error.
This patch updates the port configuration based on device capabilities
after getting the device information to support devices like virtio
and vhost.
