SSL: avoid calling SSL_write() with zero data size.
According to documentation, calling SSL_write() with num=0 bytes to be sent
results in undefined behavior.
We don't currently call ngx_ssl_send_chain() with empty chain and buffer.
This check handles the case of a chain with total data size that is
a multiple of NGX_SSL_BUFSIZE, and with the special buffer at the end.
In practice such cases resulted in premature connection close and critical
error "SSL_write() failed (SSL:)" in the error log.
