mm/hugetlb: simplify hugetlb unmap
For hugetlb like THP (and unlike regular page), we do tlb flush after
dropping ptl. Because of the above, we don't need to track force_flush
like we do now. Instead we can simply call tlb_remove_page() which will
do the flush if needed.
No functionality change in this patch.
