Actually disable CoW on @swap and @var_log

Browse source 
There is a bug with BTRFS where it uses the same mount option for the first subvolume for any subvolume you mount. That means the nodatacow flag you set on line 74 and 75 are useless. In order to disable CoW, you must add chattr +C to those.
