mm, hugetlb: remove decrement_hugepage_resv_vma()
Now, Checking condition of decrement_hugepage_resv_vma() and vma_has_reserves() is same, so we can clean-up this function with vma_has_reserves(). Additionally, decrement_hugepage_resv_vma() has only one call site, so we can remove function and embed it into dequeue_huge_page_vma() directly. This patch implement it.
