Now that vb2_shared_data / vb2_context provides all the same data to lower-level kernel verification code that cparams did, stop passing cparams down to those functions. No change in functionality. BUG=chromium:611535 BRANCH=none TEST=make -j runtests; build bob firmware and boot it Change-Id: I86eb1801ee96d8b56404b74843a8d09e3122567f Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/852814 Commit-Ready: ChromeOS CL Exonerator Bot <chromiumos-cl-exonerator@appspot.gserviceaccount.com> Reviewed-by: Stefan Reinauer <reinauer@chromium.org>
