Subject: [PATCH 10/20] wifi: iwlwifi: mvm: modify iwl_mvm_ftm_set_secured_ranging() parameters

From: Avraham Stern <[email protected]>

Modify iwl_mvm_ftm_set_secured_ranging() parameters to support
multiple versions of the target struct.
This is done as preparation for moving to the new range request
version.
