track the console buffer usage with a boolean instead of an int
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.
