pgsql: Fix bug in WAL replay of COMMIT_TS_SETTS record.

Fix bug in WAL replay of COMMIT_TS_SETTS record.

Previously the WAL replay of COMMIT_TS_SETTS record called
TransactionTreeSetCommitTsData() with the argument write_xlog=true,
which generated and wrote new COMMIT_TS_SETTS record.
This should not be acceptable because it's during recovery.

This commit fixes the WAL replay of COMMIT_TS_SETTS record
so that it calls TransactionTreeSetCommitTsData() with write_xlog=false
and doesn't generate new WAL during recovery.

Back-patch to all supported branches.
