Description
The !GDALNoDataBand class does not properly handle signed integer bands with negative nodata values because GDALNoDataMaskBand::IReadBlock() uses an UInt32 working buffer, and all negative values are truncated to zero when data is read into the buffers.

Same fix applied in r15130 for GDALNoDataValuesMaskBand that is roughly a copy&paste of GDALNoDataMaskBand

Fixed in trunk (r15126) and 1.5 branch (r15127).
