chelsio/chtls: prevent potential integer overflow on 32bit
The "gl->tot_len" variable is controlled by the user. It comes from
process_responses(). On 32bit systems, the "gl->tot_len +
sizeof(struct cpl_pass_accept_req) + sizeof(struct rss_header)" addition
could have an integer wrapping bug. Use size_add() to prevent this.
