rds: ib: force endiannes annotation

While the endiannes is being handled correctly as indicated by the comment above the offending line - sparse was unhappy with the missing annotation as be64_to_cpu() expects a __be64 argument. To mitigate this annotation all involved variables are changed to a consistent __le64 and the conversion to uint64_t delayed to the call to rds_cong_map_updated().
