zip: use offset fields in sqe to avoid SG_SPLIT

driver inclusion
category: feature
bugzilla: NA
CVE: NA

In this patch, we try to use the offset fields in sqe to avoid split
scatterlists. We can configure sgl offset fields in ZIP sqe to let
ZIP engine read/write sgl data with skipped data. Hence no need to
splite the sgl.
