xen: fix is_disconnected_device/exists_disconnected_device

The logic of is_disconnected_device/exists_disconnected_device is wrong
in that they are used to test whether a device is trying to connect (i.e.
connecting).  For this reason the patch fixes them to not consider a
Closing or Closed device to be connecting.  At the same time the patch
also renames the functions according to what they really do; you could
say a closed device is "disconnected" (the old name), but not "connecting"
(the new name).

This patch is a backport of changeset 909 from the Xenbits tree.
