Subject: [PATCH] hugetlb: factor init_nodemask_of_node()

Factor init_nodemask_of_node() out of the nodemask_of_node() macro.

This will be used to populate the huge pages "nodes_allowed" nodemask for
a single node when basing nodes_allowed on a preferred/local mempolicy or
when a persistent huge page pool page count is modified via a per node
sysfs attribute.
