From: Oleksandr Tyshchenko <oleksandr_tyshche...@epam.com>
Both state (XenbusStateClosed) and online (0) are expected by
toolstack/xl devd to completely destroy the device. But "offline"
is never being set by the backend resulting in timeout during
domain destruction, garbage in Xestore and still running Qemu
instance.
