Attila Fülöp 211ec1b9fd Deny receiving into encrypted datasets if the keys are not loaded
Commit 68ddc06b61 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.
