[PATCH] tcp: Update EPOLL_TYPE_TCP_TIMER fd

[Laurent Vivier <lvivier@redhat.com>]

For consistency with other epoll events, set the fd field to the file
descriptor actually added by epoll_ctl() (conn->timer), rather than
conn->sock.

This is a no-op change as ref.fd is not currently used in
tcp_timer_handler().
