Subject: [PATCH 37/38] tick-broadcast: merge tick_do_broadcast_on_off() into tick_broadcast_on_off()

We have added a wrapper around tick_do_broadcast_on_off() which doesn't have
anything so special that we should keep it. It just had a check if cpu is online
or not. Just merge these two routines and keep one: tick_broadcast_on_off().
This would get rid of an extra function call that we are doing currently.

This also replaces printk(KERN_ERR "**"); with pr_err("**");
