ixgbe: ixgbe_down needs to stop dev_watchdog
There is a small race between when the tx queues are stopped
and when netif_carrier_off() is called in ixgbe_down. If the
dev_watchdog() timer fires during this time it is possible for
a false tx timeout to occur.
This patch moves the netif_carrier_off() so that it is called before
the tx queues are stopped preventing the dev_watchdog timer from
detecting false tx timeouts. The race is seen occosionally when
FCoE or DCB settings are being configured or changed.
Testing note, running ifconfig up/down will not reproduce this
issue because dev_open/dev_close call dev_deactivate() and then
dev_activate().
