Subject: [PATCH 28/43] tools/kvm_stat: suppress usage information on command
 line errors

Errors while parsing the '-g' command line argument result in display of
usage information prior to the error message. This is a bit confusing,
as the command line is syntactically correct.
To reproduce, run 'kvm_stat -g' and specify a non-existing or inactive
guest.
