i40e: Do not use WQ_MEM_RECLAIM flag for workqueue

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.
