[PATCH 2/5] track the console buffer usage with a boolean instead of an int

[Marin Ramesa]

A variable that keeps track of the console buffer usage should never receive 
values other than 0 and 1, so constrain it's value range to boolean. Plus, it's
more readable this way.

* device/cons.c (consbufused): Use boolean_t instead of an int.
