[PATCH] 254: fix to pass subvolid=0 to set default btrfs subvolme

[Li Zefan]

The usage is 'btrfs subvolume set-default <id> <path>', not
'<path> <path>'.

The code happens to work because strotoull(path) returns 0, but it
will fail if in the future we check the argument more strict in
btrfs-progs.
