IB/SA: Split struct sa_path_rec based on IB and ROCE specific fields
sa_path_rec now contains a union of sa_path_rec_ib and sa_path_rec_roce based on the type of the path record. Note that fields applicable to path record type ROCE v1 and ROCE v2 fall under sa_path_rec_roce. Accessor functions are added to these fields so the caller doesn't have to know the type.
