mm/sparse: refine usemap_size() a little
The current implementation calculates usemap_size in two steps: * calculate number of bytes to cover these bits * calculate number of "unsigned long" to cover these bytes It would be more clear by: * calculate number of "unsigned long" to cover these bits * multiple it with sizeof(unsigned long) This patch refine usemap_size() a little to make it more easy to understand.
