[SCSI] tgt: fix sesnse buffer problems
This patch simplify the way to notify LLDs of the command completion and addresses the following sense buffer problems: - can't handle both data and sense. - forces user-space to use aligned sense buffer tgt copies sense_data from userspace to cmnd->sense_buffer (if necessary), maps user-space pages (if necessary) and then calls host->transfer_response (host->transfer_data is removed).
