When building the L3 HW header for non-IP packets, trust the cast type that was passed as parameter. qeth_l3_get_cast_type() has most likely also used h_dest to determine the cast type, so we get the same result, and can remove that duplicated code. In the unlikely case that we would get a _different_ cast type, then that's based off a route lookup and should be considered authoritative.
