target: simplify code around transport_get_sense_data
The error conditions in transport_get_sense_data are superfluous
and complicate the code unnecessarily:
* SCF_TRANSPORT_TASK_SENSE is checked in the caller;
* it's simply part of the invariants of dev->transport->get_sense_buffer
that it must be there if transport_complete ever returns 1, and that
it must not return NULL. Besides, the entire callback will disappear
with the next patch.
* similarly in the caller we can expect that sense data is only sent
for non-zero cmd->scsi_status.
