Subject: CVE-2024-35913: wifi: iwlwifi: mvm: pick the version of SESSION_PROTECTION_NOTIF

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:

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
