xen/blkfront: allow xenbus state transition to Closing->Closed when not Connected
commit 28afea5b2ffaa48f4f43d22ae8edcc384c05df80 upstream.
This situation can occur when attempting to attach a block device whose
backend is an empty physical CD-ROM driver. The backend in this case
will go directly from the Initialising state to Closing->Closed.
Previously this would result in a NULL pointer deref on info->gd
(xenbus_dev_fatal does not return as a1a15ac5 seems to expect)
