[SCSI] qla1280: convert to use the data buffer accessors

- remove the unnecessary map_single path.
- convert to use the new accessors for the sg lists and the parameters.

Fixed to missing initialization of sg lists before calling
for_each_sg() by Jes Sorensen - sg list needs to be initialized before
trying to pull the elements out of it.
