mm: hugetlb_vmemmap: fix hugetlb page number decrease failed on movable nodes

The decreasing of hugetlb pages number failed with the following message

The reason is that the hugetlb pages being released are allocated from
movable nodes, and with hugetlb_optimize_vmemmap enabled, vmemmap pages
need to be allocated from the same node during the hugetlb pages
releasing. With GFP_KERNEL and __GFP_THISNODE set, allocating from movable
node is always failed. Fix this problem by removing __GFP_THISNODE.
