s3:vfs:shadow_copy2: Fix shadow-copy module for drag&drop from a snapshot

Browse Source 
We have to return NT_STATUS_NOT_SAME_DEVICE to trigger the Windows client to
start a copy itself. Unbeknownst to us via the ACLs snapshots are read-only, so
a rename would trigger a EACCES. Unfortunately the MacOS/X finder does not do
the smart NOT_SAME_DEVICE fallback that Windows does.
