From: Xiang Chen <chenxian...@hisilicon.com>
Since the task prep functions now should not fail, adjust
the return types to void.
In addition, some checks in the task prep functions are
relocated to the main module; this is specifically the
check for the number of elements in an sg list exceeded
the HW SGE limit.
