wifi: iwlwifi: mvm: put only a single IGTK into FW

Browse source

The firmware only supports a single IGTK, and due to some
changes it really doesn't like to have multiple programmed
in later versions. Since only newer firmware cannot remove
a key that isn't present any more, adjust only the MLD API
code to keep track of the previous IGTK and remove it when
a new one is added.
