[NDB patch 4/5] BUG#28804 release index operation for unique index lookup (without matching tuple) on completion of operation, not txn

[stewart]

This also ensures we free TransactionBufferMemory. This would severely limit
the size of txns doing non-matching unique index lookups (as well as having
the related problem of full txn buff memory).
