[PATCH v2 6/6] ethdev: return named opaque type instead of void pointer

[Ferruh Yigit <ferruh.yigit@intel.com>]

"struct rte_eth_rxtx_callback" is defined as internal data structure and
used as named opaque type.

So the functions that are adding callbacks can return objects in this
type instead of void pointer.

v2:
* keep using struct * in parameters, instead add callback functions
return struct rte_eth_rxtx_callback pointer.
