crypto: ccree - remove special handling of chained sg
commit c4b22bf51b815fb61a35a27fc847a88bc28ebb63 upstream. We were handling chained scattergather lists with specialized code needlessly as the regular sg APIs handle them just fine. The code handling this also had an (unused) code path with a use-before-init error, flagged by Coverity. Remove all special handling of chained sg and leave their handling to the regular sg APIs.
