    x86: Remove "%!" before ret

    Before MPX was removed, "%!" was mapped to

            case '!':
              if (ix86_bnd_prefixed_insn_p (current_output_insn))
                fputs ("bnd ", file);
              return;

    After CET was added and MPX was removed, "%!" was mapped to

           case '!':
              if (ix86_notrack_prefixed_insn_p (current_output_insn))
                fputs ("notrack ", file);
              return;

    ix86_notrack_prefixed_insn_p always returns false on ret since the
    notrack prefix is only for indirect branches.  Remove the unused "%!"
    before ret.
