Fix WRITE SAME data buffer length handling

Browse Source 
From the SPC-4 paragraph about WRITE SAME(10): "The WRITE SAME (10)
command requests that the device server transfer a single logical
block from the Data-Out Buffer [ ... ]". Hence always pass a data
buffer when sending a WRITE SAME(10) command.

Set the NDOB bit in the WRITE SAME(16) command if no data out buffer
is present.
