staging: dgap: tty.c: removes smatch warning "ignoring unreachable code"

This patch removes this smatch warning: info: ignoring unreachable code. There were instances where there was extra code after the default action in switch statements. These default actions ended with a break so the code wasn't being run at anytime. This patch removes that extra code.
