[PATCH 04/17] wifi: iwlwifi: mvm: rename iwl_dev_tx_power_common::mac_context_id

[Miri Korenblit <miriam.rachel.korenblit@xxxxxxxxx>]

From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>

This is becoming the link_id. Since this makes no difference on non-MLD
devices, just rename to link_id for all the APIs that use the common
structure.

Starting from command 9, feed the link_id to the firmware instead of the
mac id.
