Modified Files:
        src/sys/dev/scsipi: cd.c

Log Message:
Fix panic on reading/writing to a (raw) CD device and encountering an
error. It now correctly sets bp->b_resid to the full size of the buffer.
The failed SCSI read/write command allways contains the complete buffer.

When encountering a read (or write) error, the scsipi stack sets the
xs->resid to zero since the command has been accepted by the drive. The
scsi command set does not allow a partial read or write to be performed and
will signal a success or an error.
