gov has already been NULL checked at the beginning of
cpuidle_switch_governor, so remove redundant check.

And use pr_info instead printk to fix the following checkpatch warning.

WARNING: Prefer [subsystem eg: netdev]_info([subsystem]dev, ... then
dev_info(dev, ... then pr_info(...  to printk(KERN_INFO ...
