[PATCH v2 0/2] btrfs-progs: fix the return value of "btrfs subvolume create"

[Qu Wenruo <wqu@suse.com>]

[CHANGELOG]
v2:
- Fix the missing "f" for the subject of the first patch
- Add the missing unmount of the test case

There is a bug report ("https://github.com/kdave/btrfs-progs/issues/730")
that after commit 5aa959fb3440 ("btrfs-progs: subvolume create: accept
multiple arguments"), "btrfs subvolume create" no longer properly return
1 for error cases.

It turns out that the offending commit changed how we determine the
return code, thus for several error cases, we still return 0 for
create_one_subvolume().

Fix it and add a test case for it.

Qu Wenruo (2):
  btrfs-progs: cmd/subvolume: fix return value when the target exists
  btrfs-progs: cli-tests: add test case for return value of "btrfs
    subvlume create"
