CONTAP-700607: Allow deletion of orphaned FlexGroup constituent (FGCV) snapshot when snapshot-locking is enabled
Issue
Customer is unable to delete an orphaned SnapMirror snapshot that exists on a FlexGroup constituent volume when snapshot-locking (SnapLock) is enabled, even when using a forced delete (e.g., -ignore-owners true -force true). The delete fails with an error indicating the operation is not allowed (returns EROFS / read-only style failure).
