net/rds: Use rdma_read_gids to read connection GIDs
Use the newly introduced rdma_read_gids() to read the SGID and DGID for the connection which returns GID correctly for RoCE transport as well. rdma_addr_get_dgid() for RoCE for client side connections returns MAC address, instead of DGID. rdma_addr_get_sgid() for RoCE doesn't return correct SGID for IPv6 and when more than one IP address is assigned to the netdevice. Therefore use transport agnostic rdma_read_gids() API provided by rdma_cm module.
