vt: keyboard.c: make console an unsigned int
[ Upstream commit 3df15d6 ] The console variable is used everywhere in some fun pointer path and array indexes and for some reason isn't always declared as unsigned. This plays havoc with some static analysis tools so mark the variable as unsigned so we "know" we can not wrap the arrays backwards here.
