cciss: fix error reporting for SG_IO

This fixes a problem with the way cciss was filling out the "errors" field
of the request structure upon completion of requests.  Previously, it just
put a 1 or a 0 in there and used the negation of this as the uptodate
parameter to one of the functions in the block layer, being a block device.
 For the SG_IO ioctl, this was not sufficient, and we noticed that, for
example, sg_turs from sg3_utils did not correctly detect problems due to
cciss having set rq->errors incorrectly.
