mm: thp: consolidate vma size check to transhuge_vma_suitable
There are couple of places that check whether the vma size is ok for THP or whether address fits, they are open coded and duplicate, use transhuge_vma_suitable() to do the job by passing in (vma->end - HPAGE_PMD_SIZE). Move vma size check into hugepage_vma_check(). This will make khugepaged_enter() is as same as khugepaged_enter_vma(). There is just one caller for khugepaged_enter(), replace it to khugepaged_enter_vma() and remove khugepaged_enter().
