Mark Syms 6bd6b955c0 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.

Also avoid creating the frontend area if it already exists.
