ixgbe: fix for race with 8259(8|9) during shutdown
There is a small window where the watchdog could be running as the
interface is brought down on a NIC with two ports wired back to back.
If ixgbe_update_status is then called can lead to a panic. This patch
allows the update to bail if we are in that condition.
This issue was orignally reported and fix proposed by Akihiko Saitou.
