Mark read event available while performing deferred accept.

Previously, the event was marked ready, but not available.  This made
EPOLLRDHUP-related code (for example, in ngx_unix_recv()) expect more data from
socket.  If SSL and PROXY protocol and deferred accept are enabled on a listen
socket, this lead to socket error.
