FreeBSD: Don't remove SA xattr if not SA znode

We attempt to remove an existing SA xattr when setting a dir xattr, but
this only makes sense if the znode has been upgraded to the SA format.
Otherwise, we will hit an assert in zfs_sa_get_xattr.

Make sure this is an SA znode before attempting to remove the SA xattr.
