[PATCH 21.11] net/af_xdp: squash deprecated-declaration warnings

[Kevin Traynor]

Fedora 37 with versions libbpf-0.8.0-2.fc37.x86_64 and
libxdp-1.2.6-1.fc37.x86_64 gives the following warnings [0].

Squash these for a clean build on Fedora 37 and any other distros
or systems using newer libbpf and libxdp versions.

Discussed on mail list at:
http://inbox.dpdk.org/dev/d718d0fe-09a2-8840-e8a4-dd41b732b391@redhat.com/
