Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes
...
the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine
has a chance to run. Since the aiRowEst now might be deleted from freeIndex()
which does not always have a db pointer, make sure the aiRowEst memory is
not held in lookaside.
