Mail: fixed SMTP pipelining to send the response immediately.
Previously, if there were some pipelined SMTP data in the buffer when a proxied connection with the backend was established, nginx called ngx_mail_proxy_handler() to send these data, and not tried to send the response to the last command. In most cases, this response was later sent along with the response to the pipelined command, but if for some reason client decides to wait for the response before finishing the next command this might result in a connection hang. Fix is to always call ngx_mail_proxy_handler() to send the response, and additionally post an event to send the pipelined data if needed.
