I've changed the code to be the mount table filter also usable for
--no-canonicalize. It seems better to avoid mnt_resolve_path() than
avoid all the filter.
It seems we can do more optimizations for huge mount tables (=autofs
issues) and canonicalizations (=NFS issues). I'll try to do it for
v2.30.1.
