mac_from_device_info is also called from __init__.py, should that be changed as well?

Small side cleanup - as the constant was unused (probably a left over from previous refactoring).

It's less likely to happen in __init__.py - as it's only called here when the mac is empty.
In config_flow it is called everytime the device is re-discovered.

Anyway - no harm in adding I guess.
