Continuing the path to support MEM_TYPE_XSK_BUFF_POOL, the AF_XDP
zero-copy/sk_buff rx_bi rings are now separate. Functions to properly
allocate the different rings are added as well.

Again, af_xdp concern is very specific to the Linux kernel, should we get this
commit in shared code drop for DPDK?
