The 'offset' data member of the 'struct scatterlist' denotes the offset
into a SG entry in bytes. But it seems that nearly all helper functions
we are using will hardcode it to ZERO. Under such a case, it seems that
take the 'offset' into accounts are just intoduce extra overhead. Waste
CPU circles, then is it correct and safe for us do some simplification
now?

v1 -> v2
	* Reword and fix typos and mistakes
