Subject: [PATCH bpf-next] libbpf: remove compile time warning from libbpf_util.h

Having a helpful compile time warning in libbpf_util.h is not a good
idea since all warnings are treated as errors. Change this into a
comment in the code instead.

Fixes: b7e3a28019c9 ("libbpf: remove dependency on barrier.h in xsk.h")
