[dpdk-dev] ret_pktmbuf_pool_init problem with opaque_arg

[Alejandro Lucero]

Inside this function mbuf_data_room_size is set to a default value if
opaque_arg is null and it should be set to the value pointed by opaque_arg
if not null. Current implementation is using not the value but with the
pointer itself. I think this:

        roomsz = (uint16_t)(uintptr_t)opaque_arg;

should be something like this:

        roomsz = *(uint16_t *)opaque_arg;
