s3:registry: update the seqnum in the subkey cache at the end of regval_store_keys

The purpose is to prevent next reads from going to disk.

Note that this will currently only be effective with local tdbs, not
with ctdb: For tdb, store and delete bump the seqnum while transaction
commit does not. For ctdb, transaction commit bumps the seqnum, while
store and delete don't... This needs fixing (in ctdb).
