Fix incorrect swizzling Y extent calculation

Browse Source 
This calculation for the amount of lines on the Y axis relative to the start of the last block was wrong and would instead determine the amount of lines to the last Y-axis GOB which wasn't accurate when padding was considered, this resulted in titles like Celeste having broken texture decoding (on a 1922x1082 texture) for the last ROB as most pixels would be masked out.
