autofs: make disc device user accessible
The autofs miscellanous device ioctls that shouldn't require CAP_SYS_ADMIN need to be accessible to user space applications in order to be able to get information about autofs mounts. The module checks capabilities so the miscelaneous device should be fine with broad permissions.
