[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).
