The unix-domain socket to AF_VSOCK multiplexers in Firecracker and
vhost-device-vsock sends OK PORT response to the client, resulting
ssh clients to abort the connection with the additional response. This
patch addresses this issue by waiting and expecting the possible OK PORT
response from the multiplexer, if any, and then handover the socket fd
to the ssh client. It only checks if the response begins with OK and
consume the response till the first \n, for simplicity.
