btrfs-progs: fix a regression that "property" with -t option doesn't work

btrfs-progs: fix a regression that "property" with -t option doesn't work

"property" is considered as working without any options
from the following commit.

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

However, we can pass -t option to this command.

* actual result

  ==================================================
  $ ./btrfs prop list -t f /btrfs
  btrfs property list: invalid option -- 't'
  usage: btrfs property list [-t <type>] <object>

      Lists available properties with their descriptions for the given object.

      Please see the help of 'btrfs property get' for a description of
      objects and object types.

  ==================================================

* expected result

  ==================================================
  $ ./btrfs prop list -t f /btrfs
  label               Set/get label of device.
  ==================================================
