rbd: correct default encryption type

Problem: When the encryptionType is not specified in the StorageClass,
the default type (block) is used and stored in OMAP. However, during
OMAP regeneration in a secondary cluster, the default type is incorrectly
set to none. This discrepancy leads to errors during PVC cloning,
with the message: `cannot create encrypted volume from unencrypted volume.`

Solution: Update the default encryption type to consistently use
block instead of none.
