Don't destroy SMgrRelations at relcache invalidation
With commit 21d9c3ee4e, SMgrRelations remain valid until end of
transaction (or longer if they're "pinned"). Relcache invalidation can
happen in the middle of a transaction, so we must not destroy them at
relcache invalidation anymore.
This was revealed by failures in the 'constraints' test in buildfarm
animals using -DCLOBBER_CACHE_ALWAYS. That started failing with commit
8af2565248, which was the first commit that started to rely on an
SMgrRelation living until end of transaction.
