Mark Johnston 6c7e4d72b1 vt: Use a taskqueue to clear splash_cpu logos 
vt_fini_logos() calls vtbuf_grow(), which reallocates the console
window's buffer using malloc(M_WAITOK).  Because vt_fini_logos() is
called via a callout, we end up panicking if INVARIANTS is enabled.

Fix the problem simply by clearing the logos using a timed taskqueue.
taskqueue_thread is formally allowed to sleep; of course, if we actually
end up sleeping to satisfy the allocation, then we have bigger problems.
