RDMA/erdma: Notify the latest PI to FW for reflushing when necessary
Firmware is responsible for flushing WRs in HW, and it's a little
difficult for firmware to get the latest PI of QPs, especially for RQs
after QP state being changed to ERROR. So we introduce a new CMDQ command,
by which driver can notify to latest PI to FW, and then FW can flush all
posted WRs.
