[PATCH] cast results of ngx_ssl_get_connection to right type

[Daniel Black]

cast the output of the ngx_ssl_get_connection to (ngx_connection_t *) since by default the macro returns a void *.

This is so we can ngx_ssl_get_connection(ssl_ctx)->log directly that assigning it to an intermediate. It will also generate a warning if we use the wrong variable type.
