mm: use numa_mem_id() in alloc_pages_node()

alloc_pages_node() might fail when called with NUMA_NO_NODE and
__GFP_THISNODE on a CPU belonging to a memoryless node.  To make the
local-node fallback more robust and prevent such situations, use
numa_mem_id(), which was introduced for similar scenarios in the slab
context.
