device: Treat devices as closed even after a close failure

Browse Source 
We require the close call, but as the underlying transport layer is
gone, it will generally just return an error.

In principle, it makes sense to think of close as a function that always
succeeds (i.e. it makes no sense to try again). Should the device be in
a bad state, then a subsequent open() will simply fail.
