Peter Zijlstra c444117f0f sched/idle: Delay clearing the polling bit 
With the generic idle functions assuming !polling we should only clear
the polling bit at the very last opportunity in order to avoid
spurious IPIs.

Ideally we'd flip the default to polling, but that means auditing all
arch idle functions.
