printk: disable preemption for printk_sched
An earlier change in -mm (printk: remove separate printk_sched
buffers...), removed the printk_sched irqsave/restore lines since it was
safe for current users. Since we may be expanding usage of
printk_sched(), disable preepmtion for this function to make it more
generally safe to call.
