Impact: fix build warning
Fix:
mm/vmscan.c: In function ‘kswapd’:
mm/vmscan.c:1969: warning: ISO C90 forbids mixed declarations and code
node_to_cpumask_ptr(cpumask, pgdat->node_id), has a side-effect: it
defines the 'cpumask' local variable as well, so it has to go into
the variable definition section.
Sidenote: it might make sense to make this purpose of these macros
more apparent, by naming them the standard way, such as:
DEFINE_node_to_cpumask_ptr(cpumask, pgdat->node_id);
(But that is outside the scope of this patch.)
