Subject: mm/buddy: get the allownodes for dump at once

When dumping the statistics for zones in the allowed nodes in the function
show_free_areas(), skip_free_areas_node() got called for multiple times to
figure out the same information: the allowed nodes for dump.  It's
reasonable to get the allowed nodes at once.  That will also help to get
consistent dump information.
