BUG 3249 : Operation Limiter not release on completion of operation

The OperationLimiter uses up one permit and per operation done on a
transaction. When that operation is complete the permit must be
released. For Local transactions this was not happening. Due to this
when a local transaction has more operations than the maximum outstanding
operations we would block for the operation timeout period (5 seconds
by default) this can have all sorts of adverse side effects on
transactions.

This patch ensures that for local transactions those permits are freed
up when the operation is complete.
