[PATCH] kasan: use \n with pr_emerg

[Vegard Nossum]

I'm seeing this in the kernel log:

    kasan: CONFIG_KASAN_INLINE enabled
    kasan: GPF could be caused by NULL-ptr deref or user memory accessgeneral protection fault: 0000 [#1] KASAN
    CPU: 0 PID: 56 Comm: ext4.exe Not tainted 4.7.0-rc6 #1

We really ought to be using \n with pr_*() so the 'general protection
fault...' starts on a line of its own. With this patch it looks better:

    kasan: CONFIG_KASAN_INLINE enabled
    kasan: GPF could be caused by NULL-ptr deref or user memory access
    general protection fault: 0000 [#1] KASAN
    CPU: 0 PID: 56 Comm: ext4.exe Not tainted 4.7.0-rc7+ #650
