Thread: pgsql: Fix rare missing cancellations in Hot Standby.

Fix rare missing cancellations in Hot Standby.
The machinery around XLOG_HEAP2_CLEANUP_INFO failed
to correctly pass through the necessary information
on latestRemovedXid, avoiding cancellations in some
infrequent concurrent update/cleanup scenarios.

Backpatchable fix to 9.0

Detailed bug report and fix by Noah Misch,
backpatchable version by me.
