Fix memory leak due to LogicalRepRelMapEntry.attrmap.
When rebuilding the relation mapping on subscribers, we were not releasing
the attribute mapping's memory which was no longer required.
The attribute mapping used in logical tuple conversion was refactored in
PG13 (by commit e1551f96e6) but we forgot to update the related code that
frees the attribute map.
