There are cases in which you want to verify that a node doesn't exist
anymore (e.g. after you have removed it), so it would be nice to return
None if the node doesn't exist.
I actually have a similar function (minus the "return None" part) in one
of my tests from the blockdev-reopen series, so I could make use of this
one instead.
