protect against failure to find a container layer win in comp

it may happen that a container layer window cannot be found (someone
deleted it other than e - which is possible), and e hasn't expected
this. comp will have removed the comp win entry but containers will
not know. this is either some client being stupid, or malicious, but
protect against it, complain with an ERR and march on so we don't crash.
