x86_64/vsyscall: Fix warn_bad_vsyscall log output
This commit in Linux 3.6:
commit c767a54ba0657e52e6edaa97cbe0b0a8bf1c1655
Author: Joe Perches <joe@perches.com>
Date: Mon May 21 19:50:07 2012 -0700
x86/debug: Add KERN_<LEVEL> to bare printks, convert printks to pr_<level>
caused warn_bad_vsyscall to output garbage in the middle of the
line. Revert the bad part of it.
The printk in question isn't actually bare; the level is "%s".
The bug this fixes is purely cosmetic; backports are optional.
