Fix bug in SPLAT taskq:front

While running SPLAT on a kernel with CONFIG_DEBUG_ATOMIC_SLEEP
enabled the taskq:front was flagged as a test which might sleep
which in an unsafe context.  Specifically, the splat_vprint()
function which internally takes a mutex was being called under
a spin lock.  Moving the log function outside the spin lock
cleanly solves this issue.
