With the introduction of bpf_link in xsk's libbpf part, there's no
further need for explicit unload of prog on xdpsock's termination. When
process dies, the bpf_link's refcount will be decremented and resources
will be unloaded/freed under the hood in case when there are no more
active users.

While at it, don't dump stats on error path.

Can we also use it from selftests prog so we have a test that is run there
using this? Looks like xdpxceiver.c could do the link step as well?

Yes! Good point!

Somehow John's mail didn't end up in my inbox.
xdpxceiver is using libbpf API for socket handling (create/delete), so
with that set included it is working on bpf_link.
