Purpose:
    Bug fix
Description:
    h5toh4 tests failed on SV1. It turned out that
    SDsetdimscale call was failing due to the wrong size of the data buffer.
    Dimension scale was not converted and shell script reported the difference
    between the actual data and the expected output.
Solution:
    File datatype instead of memory type was used to calculate the size of the
    data buffer. Used memory type.
Platforms tested:
    SV1, arabica
