[PATCH 7/8] refs: stop setting EINVAL and ELOOP in symref resolution

["Han-Wen Nienhuys via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Han-Wen Nienhuys <hanwen@xxxxxxxxxx>

The only caller of refs_resolve_ref_unsafe_with_errno() is in
refs/files-backend.c, and it only cares about EISDIR and ENOTDIR.
