mm/vmalloc: use kmalloc_array() instead of kmalloc() 

The number of NUMA nodes (nr_node_ids) is bounded, so overflow is not a
practical concern here.  However, using kmalloc_array() better reflects
the intent to allocate an array of unsigned ints, and improves consistency
with other NUMA-related allocations.

No functional change intended.
