wifi: iwlwifi: handle non-overlapping API ranges

Browse Source 
The option to set an api_version_min/max also to the RF was added.
In the case that both the MAC and the RF has a range defined, we take
the narrower range of both.

This doesn't work for non-overlapping ranges. In this case, we should
just take the lower range of both.
