    zfs: cherry-pick change from master
    
     #15465 763ca47f Fix block cloning between unencrypted and encrypted
                     datasets
    
    Fixes a kernel panic when block cloning is enabled and system is trying
    to read data from a file copied using copy_file_range(2), e.g. with cp(1)
    from an unencrypted dataset into an encrypted dataset on the same ZFS pool.
    As the file has not been encrypted, to fix the filesystem inconsistency
    and to avoid future panics it must be deleted (metadata is readable).
    
    Approved by:    re (gjb)
