btrfs-progs: subvolume sync: fix handling of -s option

Browse Source 
Setting check interval for subvolume sync resulted
in picking wrong element from argv for it's value:

  $ btrfs subvolume sync -s 10 ./dir
  ERROR: invalid sleep interval ./dir
  $ btrfs subvolume sync ./dir -s 10
  Segmentation fault
