The ucma users supply timeout in u32 format, it means that any number with most significant bit set will be converted to negative value by various rdma_*, cma_* and sa_query functions, which treat timeout as int. In the lowest level, the timeout is converted back to be unsigned long. Remove this ambiguous conversion by updating all function signatures to receive unsigned long.
