Wei Yang 6664bfc8e9 mm/hugetlb: take the free hpage during the iteration directly
Function dequeue_huge_page_node_exact() iterates the free list and return
the first valid free hpage.

Instead of break and check the loop variant, we could return in the loop
directly.  This could reduce some redundant check.
