…upported CephFS mirroring unconditionally attempted to initialize blockdiff, causing initialization failure on older Ceph clusters where blockdiff is not supported but mirror daemon supporting blockdiff. This breaks backward compatibility and prevents the mirror daemon from syncing. Fix this by detecting blockdiff support and initializing it only when supported, allowing mirroring to function correctly with older Ceph versions.
