mm/khugepaged: keep mm in mm_slot without MMF_DISABLE_THP check
Previously, we removed the mm from mm_slot and dropped mm_count if the MMF_THP_DISABLE flag was set. However, we didn't re-add the mm back after clearing the MMF_THP_DISABLE flag. Additionally, We add a check for the MMF_THP_DISABLE flag in hugepage_vma_revalidate().
