x86: remove stray <6> in BogoMIPS printk

Rabin Vincent noticed that there's a stray <6> in BogoMIPS printk:

> Remove the extra KERN_INFO which causes this:
> Calibrating delay loop... <6>179.40 BogoMIPS (lpj=897024)
> -	printk(KERN_INFO "%lu.%02lu BogoMIPS (lpj=%lu)\n",
> -			loops_per_jiffy/(500000/HZ),
> -			(loops_per_jiffy/(5000/HZ)) % 100, loops_per_jiffy);
> +	printk("%lu.%02lu BogoMIPS (lpj=%lu)\n",
> +		loops_per_jiffy/(500000/HZ),
> +		(loops_per_jiffy/(5000/HZ)) % 100, loops_per_jiffy);
>  }

How about just using KERN_CONT and leaving the whitespace
for a patch that does the entire file?
