bpf: Check netfilter ctx accesses are aligned
Similarly to the previous patch fixing the flow_dissector ctx accesses,
nf_is_valid_access also doesn't check that ctx accesses are aligned.
Contrary to flow_dissector programs, netfilter programs don't have
context conversion. The unaligned ctx accesses are therefore allowed by
the verifier.
Fixes: fd9c663b9ad6 ("bpf: minimal support for programs hooked into netfilter framework")
