RDMA/irdma: Fix RQ completion opcode
The opcode written by HW, in the RQ CQE, is the
RoCEv2/iWARP protocol opcode from the received
packet and not the SW opcode as currently assumed.
Fix this by returning the raw operation type and
queue type in the CQE to irdma_process_cqe and add
2 helpers set_ib_wc_op_sq set_ib_wc_op_rq to map
IRDMA HW op types to IB op types.
Note that for iWARP, only Write with Immediate is
supported so the opcode can only be IB_WC_RECV_RDMA_WITH_IMM
when there is immediate data present.
Fixes: b48c24c2d710 ("RDMA/irdma: Implement device supported verb APIs")
