eet data encode - dont free data if its not separately allocated

in one case data is not separately allocated but is part of the
Eet_Variant_Unknow struct where it is allocated as extra space on the
end of the data blob. in this case don't free it, otherwise do (pass
in true) as before. this should fix CID 1039728
