Running zfs_acl_chmod_inherit_003_pos, the following portion of it fails, leading to a failed test:

13:30:39.62 ERROR: usr_exec mkdir -p /var/tmp/testdir/basedir/ndir1/ndir2/ndir3 exited 2

The error happens when dataset has property aclinherit=passthrough, the current user is set to non-root.

The problem there is that non-root user was set no permissions (other than AW and Co),
that is the reason why mkdir is reporting permission denied. Adding owner to have rwxp
does allow mkdir to succeed and test can complete with SUCCESS.

Testing done: run zfstest.
