liquidio: Prioritize control messages
During heavy tx traffic, control messages (sent by liquidio driver to NIC
firmware) sometimes do not get processed in a timely manner. Reason is:
the low-level metadata of control messages and that of egress network
packets indicate that they have the same priority.
Fix it by setting a higher priority for control messages through the new
ctrl_qpg field in the oct_txpciq struct. It is the NIC firmware that does
the actual setting of priority by writing to the new ctrl_qpg field; the
host driver treats that value as opaque and just assigns it to pki_ih3->qpg
