CVE-2024-36004

In the Linux kernel, the following vulnerability has been resolved: i40e:
Do not use WQ_MEM_RECLAIM flag for workqueue Issue reported by customer
during SRIOV testing, call trace: When both i40e and the i40iw driver are
loaded, a warning in check_flush_dependency is being triggered. This seems
to be because of the i40e driver workqueue is allocated with the
WQ_MEM_RECLAIM flag, and the i40iw one is not. Similar error was
encountered on ice too and it was fixed by removing the flag. Do the same
for i40e too. [Feb 9 09:08] ------------[ cut here ]------------ [
