    gas: dw2gencfi: reset reloc to TC_PARSE_CONS_RETURN_NONE for [su]leb128
    
    Some consumers, like SFrame generation logic in GAS, may want to check
    reloc value (without qualifying by e->type) as a part of their
    admissibility criteria.  Setting reloc to TC_PARSE_CONS_RETURN_NONE for
    these CFI escape expr nodes for [su]leb128 keeps the admissibility
    checks simple and generic.
