Revert "regdb: use dbwrap->fetch() instead of fetch_locked() for readonly access"

This reverts commit 4e2be189e97f653b75bd88135a631ce0f42db267.

Metze, this broke the registry (reg_api layer), but I don't yet know
exactly how and why. By the way, the locks there had the purpose of
fetching the seqnum that really matches the data.

This needs some more thought / debugging. But I wanted to have
the tree in a working state again.
