    sh: Idle loop chainsawing for SMP-based light sleep.

added a call to local_irq_disable() to cpu_idle(), which, if the cpuidle driver
is used, now stays unbalanced. This patch re-adds the missing
local_irq_enable().

Unfortunately, even after this patch CPU_IDLE is still broken on sh, due 
to some later PM changes, so, I'll remove it from all defconfigs with the 
following patch.
