wifi: iwlwifi: mvm: align to the LINK cmd update in the FW

The LINK cmd host api has been updated. Align the driver to the
new changes. Also, temporary use mac_id for link_id.
Using the phy_id as the link_id is wrong since we might have 2 macs
operating on the same phy - in this case we will have 2 different
links (one for each mac) with the same link_id. On the other hand,
since we don't have MLO implemented yet, we won't have 2 different
links of the same mac. Therefore, we can use the mac_id as the
link_id.
