If I get it correctly, the selected_console/preferred_console
value is used to keep the console first in the console_drivers list.
IMHO, the main effect is that each line will first appear on this
console, see call_console_drivers(). But the message will still
appear also on all other enabled consoles. From this point,
the name "preferred" sounds better to me. More consoles
are selected (enabled) and only one is preferred (first).

Well, I am not a native speaker and might be wrong. Also
it is possible that I missed something.

Anyway, the change looks fine to me.
