Subject: [PATCH] sha1: don't clean local variable i on exit

In this place value of variable i is constant and predictable. No point
to clean it. Furthermore, since the value is not used after assignment,
compiler will optimize and remove the assignment.

This patch fixes a warning from the clang static analyzer.
