From: Jens Axboe <axboe@suse.de>
For the flush generated requests, we don't have room for sense info right
now. This might change in the future so that the sd end_io function can
make a better judgement on what to do about an error. So check this in
scsi_io_completion(), only copy sense data to request if it has space
assigned to it.
