[svn-r8936]
Purpose: Bug fix
Description: While working on the SZIP documentation with Frank, I realized
that when scanline was less than 4k and bigger than pixels_per_block,
it was not adjusted if number_of_blocks_per_scanline was bigger
than max_number_of_blocks_per_scanline.
Solution: Fixed the code. Unfortunately it didn't help with the problem
I had using h5repack with DOQGROD.he5 file.
Platforms tested: copper
