kvm tools: Fix wrong kill() PID in commands

There was a mixup in the balloon usage string and some of the commands were
retrieving the instance name from the wrong place. This will cause the commands
to issue kill() with negative PIDs (which sends the signal to every process in
the system). Without this patch, 'kvm command instance' will do crazy things
like restart whole Gnome session.
