cpumask: remove cpumask allocation from idle_balance
Impact: fix circular locking
Steven reports a circular locking from alloc_cpumask_var doing
a wakeup. We get rid of this using the tried-and-true technique
of using a per-cpu cpumask_var_t rather than doing an alloc
every time.
Simpler and more robust than a rare, implicit allocation within
an atomic codepath.
