Add stop function to management interface.
It is needed for error handling when execution has to be aborted early.
Example flow:
```
rc = op();
if (rc) {
handle();
vbdev_ocf_mngt_stop();
} else {
vbdev_ocf_mngt_continue();
}
```
This can be improved in the future, because currently, error
handling cannot be a management operation on its own (but should be).
