target: Fix WRITE_SAME usage with transport_get_size
For all flavours of WRITE_SAME, we only expect to handle a single block of data-out buffer payload, regardless of the number of logical blocks presented in the CDB. This patch changes all flavours of WRITE_SAME in transport_generic_cmd_sequencer() to pass '1' into transport_get_size() instead of the extracted 'sectors' to properly handle the default usage of sg_write_same without the --xferlen parameter.
