[PATCH 3/5] track the console init with a boolean instead of an int

[Marin Ramesa]

A variable that keeps track if the console init has been called. It should
never receive values other than 0 and 1, so constrain it's possible range of 
values to a boolean.

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