Make ReadData exception logging less noisy

There is some component (openflow) which is reading data on a ClosedTransaction.
This is causing logging on the datastore side. The component itself seems to handle
the error reported by the datastore quietly, so switching the logging the error to
debug and logging full stack trace at trace level.
