WAIT FOR LSN registers the current backend in shared memory before entering an interruptible wait loop. Top-level abort and backend exit already call WaitLSNCleanup(), but subtransaction abort did not. If an interrupt, such as statement_timeout, occurred while waiting inside a savepoint, rolling back to the savepoint left the backend marked as present in the WAIT FOR LSN heap. Clean up WAIT FOR LSN state from AbortSubTransaction() as well, and add a TAP test covering reuse of WAIT FOR LSN after a savepoint rollback.
