 Cloned from #4041:
 ----
 If the mount for a dosfs (FAT) fails, the `converter` that is used to
 encode and decode the file names is not destroyed. That will lead to
 memory leaks.

 Note that there are two cases:

 1. User doesn't provide a converter. In this case a default converter is
 created implicitly.

 2. User does provide a converter.

 Both have to be handled slightly different.
