previously, if multiple mount option was passed it was
handing it wrong. For example,
```
ms_mode=prefer-secure,recover_session=clean
```
was treated as
```
ms_mode: prefer-secure,recover_sessio
```
With current fix it handles it correctly. Example,
```
ms_mode: prefer-secure,
recover_session=clean,
```
