Commit 68ddc06 introduced support for receiving unencrypted datasets as children of encrypted ones but unfortunately got the logic upside down. This resulted in failing to deny receives of incremental sends into encrypted datasets without their keys loaded. If receiving a filesystem, the receive was done into a newly created unencrypted child dataset of the target. In case of volumes the receive made the target volume undeletable since a dataset was created below it, which we obviously can't handle. Incremental streams with embedded blocks are affected as well. We fix the broken logic to properly deny receives in such cases.
