target: Add compare_and_write_post() completion callback fall through
This patch changes target_complete_ok_work() to fall through
after calling the se_cmd->transport_complete_callback() ->
compare_and_write_post() callback, by keying off the existance
of SCF_COMPARE_AND_WRITE_POST.
This is necessary because once SCF_COMPARE_AND_WRITE_POST has
been set by compare_and_write_post(), the SCSI response needs
to be sent via TFO->queue_status().
