With the introduction of bpf_link in xsk's libbpf part, there's no

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?
