rtas_cpu_state_change_mask() potentially operates on scores of cpus,
so explicitly allow rescheduling in the loop body.

Are we seeing softlockups/rcu stalls while running this ?

I have not seen a report yet, but since the loop is bound only by the
number of processors in the LPAR I suspect it's only a matter of time.
