refs API: make loose_fill_ref_dir() not set errno

avar · gitster · commit 096a7fbb97dc · 2021-10-16T11:17:03.000-07:00
Change the refs_resolve_ref_unsafe() invoked in loose_fill_ref_dir()
to a form that ignores errno. The only eventual caller of this
function is create_ref_cache(), whose callers in turn don't have their
failure depend on any errno set here.
