This patch set cleans up and reorganizes the driver's net_device
close function and leverages that to fix up a bug that can occur
during some device resets. Some reset cases require the backing
adapter to be disabled before continuing, but other cases, such as 
during a device failover or partition migration, do not require this
step. Since the device will not be initialized at this stage and
its command-processing queue is closed, do not send the request to
disable the device as it could result in an error or timeout
disrupting the reset.
