Thanks for making the requested changes.

There is a remaining issue with this patch, creating a flow in isolated mode
causes a crash due to RX QPs not being allocated. You should temporarily
make priv_flow_create_action_queue() call rxq_create_qp() when the target QP
does not exist.

Patch looks otherwise fine.
