Petr Mladek 40f7828b36 btrfs: better handle btrfs_printk() defaults
Commit 262c5e86fec7 ("printk/btrfs: handle more message headers")
triggers:

    warning: `ratelimit' may be used uninitialized in this function

with gcc (4.1.2) and probably many other versions.  The code actually is
correct but a bit twisted.  Let's make it more straightforward and set
the default values at the beginning.
