    Only do frame payload check for HOLD frames.
    
    This code was added for helping to debug the source of invalid HOLD frames.
    However, a side effect of this is that it will incorrectly report errors for
    frames that have an integer payload.  Make the check for this block specific
    to the HOLD frame case.
