btrfs-progs: "device ready" accepts just one device

* actual result

  =======================================
  # ./btrfs device ready /dev/sdb foo
  #
  =======================================

* expecting result

  =======================================
  # ./btrfs device ready /dev/sdb foo
  btrfs device ready: too many arguments
  usage: btrfs device ready <device>

      Check device to see if it has all of its devices in cache for mounting
