Subject: [PATCH net-next-2.6] vxge: add missing flush of reset_task

Commit 6e07ebd84 (drivers/net: remove unnecessary
flush_scheduled_work() calls) incorrectly removed the flush call
without replacing it with the appropriate work specific operation.
Fix it by flushing vdev->reset_task explicitly.

Pointed out by Jon Mason.
