VPP-279: af_packet via Command-line Arg should no longer be supported

With the CLI command 'create host-interface', no longer need to
support af_packet interface creation via Command-line Arg. However,
this is mostly implemented by passing arguments to DPDK. Instead of
blocking functionality, put a warning in the log directing the user
to the CLI.
