scsi: fcoe: open-code fcoe_destroy_work() for NETDEV_UNREGISTER
When a NETDEV_UNREGISTER notification is received the network device is
_deleted_ after the callback returns. So we cannot use a workqueue
here, as this would cause an inversion when removing the device as the
netdev is already gone. This manifests with a nasty warning during
shutdown:
sysfs group ffffffff81eff0e0 not found for kobject 'fc_host7'
So open-code fcoe_destroy_work() when receiving the notification to
avoid this inversion.
