[PATCH] cooker: Only change self.data if it exists

[Richard Purdie <richard.purdie@linuxfoundation.org>]

With the change to more optimal default featureset behaviour, a race was
exposed by hob where the code may try and change self.data before it
exists. This change avoids that.

When the datastore is created, the cooker configuration is used so
data tracking is correctly handled regardless.
