Remove the error "branch '%s' does not point at a commit" in
append_ref(), which reports branch refs which do not point to
commits. Also remove the error "some refs could not be read" in
print_ref_list() which is triggered as a consequence of the first
error.
The purpose of these codepaths is not to diagnose and report a
repository corruption. If we care about such a corruption, we
should report it from fsck instead, which we already do.
This also helps in a smooth port of branch.c to use ref-filter APIs
over the following patches. On the other hand, ref-filter ignores refs
which do not point at commits silently.
