CVE-2024-26694

In the Linux kernel, the following vulnerability has been resolved: wifi:
iwlwifi: fix double-free bug The storage for the TLV PC register data
wasn’t done like all the other storage in the drv->fw area, which is
cleared at the end of deallocation. Therefore, the freeing must also be
done differently, explicitly NULL’ing it out after the free, since
otherwise there’s a nasty double-free bug here if a file fails to load
after this has been parsed, and we get another free later (e.g. because no
other file exists.) Fix that by adding the missing NULL assignment.
