GDALNoDataMaskBand::IReadBlock doesn't behave correctly when eWrkDT != eDataType

Description
Incorrect behaviour will happen if eWrkDT != eDataType, and possibly crash if sizeof(eDataType) > sizeof(eWrkDT).
The fix is to do a RasterIO with the working data type instead of doing a ReadBlock (that uses the natural data type).

Fixed in trunk in r15030 and in branches/1.5 in r15031
