> If a reset fails to complete, the driver gets its affairs in order and awaits the
> cold solace of rmmod. Unfortunately, it was not properly setting the adapter
> state, which would cause a panic on rmmod, instead of the desired surcease.
> 
> Set the adapter state to DOWN in this case, and avoid a panic.
