Avoid unnecessary error messages from hwcomposer under crosvm

When the vnc server isn't started, there is no vsock server on the
host for the hwcomposer to connect to, so it fails its connection
attempt, logs it and continues working without sending the composed
frames to the host. Instead, it shouldn't even try to connect when the
server is known to not be available.

Test: run locally
