Error on HA Shutdown about midea_ac_lan

[georgezhao2010]

This exception always gets thrown during graceful HA shutdown; if you could catch it so it doesn't fire off people's alerting around exceptions that would be lovely!

I'd also be happy to take a stab at fixing it if it's not a high priority for you!

I'll fix it, and thank you.
