RDMA/bnxt_re: Allow MSN table capability check
FW reports the HW capability to use PSN table or MSN table and
driver/library need to select it based on this capability.
Use the new capability instead of the older capability check for HW
retransmission while handling the MSN/PSN table. FW report
zero (PSN table) for older adapters to maintain backward compatibility.
Also, Updated the FW interface structures to handle the new fields.
