Samba plugin - CIFS: VFS: Malformed UNC in devname

[alexcustos]

Describe the issue you are experiencing

Samba plugin offers the smb://<IP_ADDRESS> file system, and it works with some clients, but it's an incorrect naming, and it doesn't work in /etc/fstab.
The address has to include a resource name like smb://<IP_ADDRESS>/share_name.
It's a bit annoying to have a mount point for each folder.
