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.
