I'd prefer to have lost-messages reporting be less of a summary
and more of an "error". I think the sooner we report it the better.
I don't think that the time we need to print lost-messages on the
consoles is significant enough to worry about it; if call_console_drivers()
becomes such a problem that any extra char we print causes message-drop then
we can disable printk_time or/and printk caller_id prefix printout (can
save us more CPU cycles).
