Nicolas Iooss 62d16b5a3f x86/mm/kaslr: Fix -Wformat-security warning 
debug_putstr() is used to output strings without using printf-like
formatting but debug_putstr(v) is defined as early_printk(v) in
arch/x86/lib/kaslr.c.

This makes clang reports the following warning when building
with -Wformat-security:

    arch/x86/lib/kaslr.c:57:15: warning: format string is not a string
    literal (potentially insecure) [-Wformat-security]
            debug_putstr(purpose);
                         ^~~~~~~

Fix this by using "%s" in early_printk().
