khugepaged: use helper function range_in_vma() in collapse_pte_mapped_thp()
Patch series "Cleanup for khugepaged". This series contains cleanups to remove unnecessary out label and meaningless !pte_present() check. Also use helper function to simplify the code. More details can be found in the respective changelogs. This patch (of 3): We could use helper function range_in_vma() to check whether the desired range is inside the vma to simplify the code.
