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.

Currently, inline send and inline write assume a single
SGE and only copy data from the first one. Add support
for multiple SGE's.

A number of asynchronous event (AE) ids were not aligned to the
correct flush_code and event_type. Fix these up so that the
correct IBV error and event codes are returned to application.
Also, add handling for new AE ids like IRDMA_AE_INVALID_REQUEST to
return the correct WC error code.

In the function irdma_post_recv, the function irdma_copy_sg_list is
not needed since the struct irdma_sge and ib_sge have the similar
member variables. The struct irdma_sge can be replaced with the
struct ib_sge totally.
This can increase the rx performance of irdma.

When the retry counter exceeds, as the remote QP didn't send any Ack or
Nack an asynchronous event (AE) for too many retries is generated. Add
code to handle the AE and set the correct IB WC error code
IB_WC_RETRY_EXC_ERR.
