scatterlist: make sure sg_miter_next() doesn't return 0 sized mappings Impact: fix not-so-critical but annoying bug sg_miter_next() returns 0 sized mapping if there is an zero sized sg entry in the list or at the end of each iteration. As the users always check the ->length field, this bug shouldn't be critical other than causing unnecessary iteration. Fix it.
