f2fs: fix a bug of inheriting default ACL from parent

Introduced by a6dda0e63e97122ce9e0ba04367e37cca28315fa
"f2fs: use generic posix ACL infrastructure".

When testing default acl, gets in recent kernel (3.19.0-rc5),
user::rwx
group::r-x
other::r-x
default:user::rwx
default:group::r-x
default:group:root:rwx
default:mask::rwx
default:other::r-x

]# getfacl testdir/
user::rwx
group::rwx
                // missing an acl "group:root:rwx" inherited from parent
other::r-x
default:user::rwx
default:group::r-x
default:group:root:rwx
default:mask::rwx
default:other::r-x
