Subject: [PATCH] selftests: net: tls: remove unused variable and code

When building selftests/net with clang, the compiler warn about the
function abs() see below:

tls.c:657:15: warning: variable 'len_compared' set but not used [-Wunused-but-set-variable]
        unsigned int len_compared = 0;
                     ^

Rework to remove the unused variable and the for-loop where the variable
'len_compared' was assinged.
