This concerns a label_ref, not a symbol_ref.  Note that I've changed
nothing wrt how symbol_ref gets handled in that function:

-  XSTR (sym, 0) = concat (SH_DATALABEL_ENCODING, XSTR (sym, 0), NULL);

i.e. previously we modified the symbol_ref in place, so indeed all
references to that symbol will act the same way.
