[PATCH] x86: Remove spurious printk level from segfault message

[Roland Dreier <roland@digitalvampire.org>]

Since commit 5fd29d6c ("printk: clean up handling of log-levels and
newlines"), the kernel logs segfaults like:

    <6>gnome-power-man[24509]: segfault at 20 ip 00007f9d4950465a sp 00007fffbb50fc70 error 4 in libgobject-2.0.so.0.2103.0[7f9d494f7000+45000]

with the extra "<6>" being KERN_INFO.  This happens because the printk
in show_signal_msg() started with KERN_CONT and then used "%s" to pass
in the real level; and KERN_CONT is no longer an empty string, and
printk only pays attention to the level at the very beginning of the
format string.

Therefore, remove the KERN_CONT from this printk, since it is now
actively causing problems (and never really made any sense).
