Subject: Various static checker fixes

I was playing around with LLVM's static checker. Here are some fixes
from reviewing the output on a kernel build.

Some merely shut up the checker -- it is technically right, but
the problem is not a real bug as far as I can tell. Still it's
cleaner/clearer to avoid uninitialized variables and similar.

A few others are real bugs.
