[PATCH] cpu_exclusive sched domains build fix

As reported by Paul Mackerras <paulus@samba.org>, the previous patch
"cpu_exclusive sched domains fix" broke the ppc64 build with
CONFIC_CPUSET, yielding error messages:

kernel/cpuset.c: In function 'update_cpu_domains':
kernel/cpuset.c:648: error: invalid lvalue in unary '&'
kernel/cpuset.c:648: error: invalid lvalue in unary '&'

On some arch's, the node_to_cpumask() is a function, returning
a cpumask_t.  But the for_each_cpu_mask() requires an lvalue mask.

The following patch fixes this build failure by making a copy
of the cpumask_t on the stack.
