mm: vmscan: modify an easily misunderstood function name

When looking at the code in the memory part, I found that the purpose of
the function prepare_scan_countis very different from the function name.
It is easy to misunderstand when reading.The function prepare_scan_count
mainly completes the assignment of the scan_control structure.Therefore, I
suggest that the function name can be changed to prepare_scan_control,
which is easier to understand.
