devices: use case-insensitive comparison for model

Browse source 
Recently, the sorting of the devices was changed to be
case-insensitive for models for consistency reasons. However,
then the equality-comparison should also be case-insensitive.

Break it out into its own function, to avoid that mistake
in the future.
