description:
SSL: reset ready flag if recv(MSG_PEEK) found no bytes in socket.
Previously, connection hung after calling ngx_http_ssl_handshake() with
rev->ready set and no bytes in socket to read. It's possible in at least the
following cases:
- when processing a connection with expired TCP_DEFER_ACCEPT on Linux
- after parsing PROXY protocol header if it arrived in a separate TCP packet
Thanks to James Hamlin.
