Introduce alloc_and_scatter_data_area()/gather_and_free_data_area() functions that allocate/deallocate space from the data area and copy data to/from a given scatter-gather list. These functions are needed so the next patch, introducing support for bidirectional commands in TCMU, can use the same code path both for t_data_sg and for t_bidi_data_sg.
