Obviously, the KVMI_GET_VERSION command must not be used when the command reply is disabled by a previous KVMI_CONTROL_CMD_RESPONSE command. This commit changes the code path in order to check the reply option (enabled/disabled) before trying to reply to this command. If the command reply is disabled it will return an error to the caller. In the end, the receiving worker will finish and the introspection socket will be closed.
