Subject: mm: remove node's validity check in alloc_pages
From: Minchan Kim <minchan.kim@gmail.com>

alloc_pages() calls alloc_pages_node() with numa_node_id(). 
alloc_pages_node can't see nid < 0.

So we can use alloc_pages_exact_node() instead of alloc_pages_node().  It
could avoid comparison and branch as 6484eb3e2a81807722 ("page allocator:
do not check NUMA node ID when the caller knows the node is") tried.
