RDMA/bnxt_re: Report out of sequence hw counters
Expose out of sequence errors received from FW. This counter is a 32 bit
counter and driver has to accumulate the counter. Stores the previous
value for calculating the difference in the next query.
Also, update the HW statistics structure with new fields.
