Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: mvm: pick the version of SESSION_PROTECTION_NOTIF

When we want to know whether we should look for the mac_id or the
link_id in struct iwl_mvm_session_prot_notif, we should look at the
version of SESSION_PROTECTION_NOTIF.

This causes WARNINGs:
