btrfs-progs: subvol get-default: fix argument parsing 

"sub get-default" does't work since the following commit.

commit 176aeca9a148 ("btrfs-progs: add getopt stubs where needed")

* actual result

   ==================================================
   # ./btrfs sub get-default /btrfs
   btrfs subvolume get-default: too few arguments
   usage: btrfs subvolume get-default <path>

       Get the default subvolume of a filesystem
   ==================================================

* expected result

   ==================================================
   # btrfs sub get-default /btrfs
   ID 5 (FS_TREE)
   ==================================================
