io: fix incoming client socket initialization

The channel socket was initialized manually, but forgot to set
QIO_CHANNEL_FEATURE_SHUTDOWN. Thus, the colo_process_incoming_thread
would hang at recvmsg. This patch just call qio_channel_socket_new to
get channel, Which set QIO_CHANNEL_FEATURE_SHUTDOWN already.
