smbd: fail replay operation on handle that has been used

Using a handle, eg processing an SMB2_WRITE operation, removes the replay cache
record associated with open.

If the handle is a Persistent Handle, the replay must fail with
NT_STATUS_FILE_NOT_AVAILABLE in this case, whereas for a Durable Handle without
persistency, the replay would be handled as a new create.
