splat: Fix log buffer locking

The Fedora 3.6 debug kernel identified the following issue where
we call copy_to_user() under a spin lock().  This used to be safe
in older kernels but no longer appears to be true so the spin
lock was changed to a mutex.  None of this code is performance
critical so allowing the process to sleep is harmless.
