ionic: always use rxq_info

ionic: always use rxq_info

Instead of setting up and tearing down the rxq_info only when the XDP
program is loaded or unloaded, we will build the rxq_info whether or not
XDP is in use.  This is the more common use pattern and better supports
future conversion to page_pool.  Since the rxq_info wants the napi_id
we re-order things slightly to tie this into the queue init and deinit
functions where we do the add and delete of napi.
