By cleaning up the driver state all devices will become inaccessible, which means that is neither possible to query any information from it (like sample rate) and it is also not possible to restart data acquisition.
sr_session_save() tries to query the sample rate from the device, as a result calling sr_session_save() after calling sr_session_stop() - which is for example done by sigrok-cli - will cause a segfault. This patch resolves the issue.
