The method had a fallback path when allocating a temporary buffer of the size of the one passed ot the method, that intended to use a less memory intensive block-based approach, but this was buggy. Fix this, and add testing for the fallback. Also, when attempting the fallback, emits a CE_Warning instead of a CE_Failure. Fixes rasterio/rasterio#3028
