qemu-io: Exit with error when a command failed
Currently, qemu-io basically always returns success when it gets to
interactive mode (so once the whole command line has been parsed; even
before the commands on the command line are interpreted). That is not
very useful.
This patch makes qemu-io return failure when any of the executed
commands failed.
