CVE-2024-36004

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

i40e: Do not use WQMEMRECLAIM flag for workqueue

Issue reported by customer during SRIOV testing, call trace: When both i40e and the i40iw driver are loaded, a warning in checkflushdependency is being triggered. This seems to be because of the i40e driver workqueue is allocated with the WQMEMRECLAIM 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.
