Simplified ngx_http_init_listening(). There is no need to set "i" to 0, as it's expected to be 0 assuming the bindings are properly sorted, and we already rely on this when explicitly set hport->naddrs to 1. Remaining conditional code is replaced with identical "hport->naddrs = i + 1". Identical modifications are done in the mail and stream modules, in the ngx_mail_optimize_servers() and ngx_stream_optimize_servers() functions, respectively. No functional changes.
