mm/sparse.c: check __highest_present_section_nr only for a present section
When searching a present section, there are two boundaries:
* __highest_present_section_nr
* NR_MEM_SECTIONS
And it is known, __highest_present_section_nr is a more strict boundary
than NR_MEM_SECTIONS. This means it would be necessary to check
__highest_present_section_nr only.
