[PATCH bpf-next v4 6/7] libbpf: Fix typos in comments

[Hemanth Selam]

Fix typos in comments, reported by scripts/checkpatch.pl using the
misspelling list in scripts/spelling.txt.  Only touches comments, no code
changes.

The subject changed since v1, from "tools/lib: fix typos in comments":
both files are under tools/lib/bpf/, where the prevailing form is
"libbpf: Fix ...".
