Move the check for check_refname_format from lock_any_ref_for_update
to lock_ref_sha1_basic. At some later stage we will get rid of
lock_any_ref_for_update completely.

This leaves lock_any_ref_for_updates as a no-op wrapper which could be removed.
But this wrapper is also called from an external caller and we will soon
make changes to the signature to lock_ref_sha1_basic that we do not want to
expose to that caller.
