[201911][Arista] Update Arista submodule to include pmbus fix (#7723)

#### Why I did it
Microsoft reported occasional daemon crashes on devices running 201911. On close inspection it was due to PMBus reads failing on IOError on very rare occasions.

#### How I did it
Add try/except block on performing reads on PMBus GPIOs.
