i40e: Do not use WQ_MEM_RECLAIM flag for workqueue

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.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
