xen-bus: only set the xen device frontend state if it is missing
Some toolstack implementations will set the frontend xenstore keys to Initialising which will then trigger the in guest PV drivers to begin initialising and some implementations will then set their state to Closing. If this has occurred then device realize must not overwrite the frontend keys as then the handshake will stall.
