mm/khugepaged: remove unnecessary goto 'skip' label

Patch series "mm/khugepaged: cleanups and scan limit fix", v3.

This series contains several cleanups for mm/khugepaged.c to improve code
readability and type safety, and one functional fix to ensure
khugepaged_scan_mm_slot() correctly accounts for small VMAs towards scan
limit.


This patch (of 4):

Replace goto skip with actual logic for better code readability.

No functional change.
