Workaround for failing tests when DEBUG=1
Two changes here.
First are some failing assertions in tlcl.c. These have always failed, but
only when DEBUG=1, so no one noticed. I've opened a bug to find out why, but
it's blocking something else. We're refactoring anyway, so for now we'll
just comment around it.
Second is a null-pointer dereference in VbSharedDataSetKernelKey(). Again,
only when DEBUG=1.
BUG=chromium:379255
BRANCH=ToT
TEST=manual
cd src/platform/ec
\rm -rf build
DEBUG=1 make runtests
