[PATCH 1/3] Btrfs: fix check_path_shared so it returns the right value

[Josef Bacik <josef@redhat.com>]

When running xfstests 224 I kept getting ENOSPC when trying to remove the files,
and this is because we were returning ret from check_path_shared while it was
uninitalized, which isn't right.  Fix this to return 0 properly, and now
xfstests 224 doesn't freak out when it tries to clean itself up.  Thanks,
