Intializing DU removal time for picture timing SEI message

Description

When HM-9.1-dev (after r3199) is run with VUI parameters on and signalling picture timing SEI message, some of the DU removal increments are set negative value. The errors occurs duee to the code at line 1521 in TEncGop.cpp (below).

if( (Int)pCRD[ i ] < 0 )
{

pCRD[ i ] ++;

}

The lines should be

if( (Int)pCRD[ i ] < 0 )
{

pCRD[ i ] = 0;

}

The reason is that the value of variable pCRD[i] derived before this line could be -2 or lower based on the difference between the values of removal time of that DU (calculated based on the number of bits) and succeeding DUs in decoding order (calculated based on the pCRD values; pCRD values are non-negative).
