Add an option to create a normal flow steering rule that doesn't trap
received packets, allowing them to match lower prioritized rules.

When the don't trap rule exists and matches a packet, the underlying HCA
should pass the packet to the rule's assigned QP(s). However, the HCA
will continue looking for other matches at lower priority rules, which
may be assigned to other QPs. This will let them get the traffic as
well.
