Don't allow relminmxid to go backwards during VACUUM FULL
We were allowing a table's pg_class.relminmxid value to move backwards
when heaps were swapped by VACUUM FULL or CLUSTER. There is a
similar protection against relfrozenxid going backwards, which we
neglected to clone when the multixact stuff was rejiggered by commit
0ac5ad5134f276.
Backpatch to 9.3, where relminmxid was introduced.
