Fix multixact members truncation at page boundary Like in PerformOffsetsTruncation() and e.g. in TruncateSUBTRANS(), need to step back to previous page at page boundary, to avoid passing a cutoff page to SimpleLruTruncate() that hasn't been created yet. Otherwise you can get a bogus 'LOG: could not truncate directory "pg_multixact/members": apparent wraparound' message in the log.
