[PATCH spice-server 06/10] tests: Avoid some possible not initialized warning from Clang

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

Not really possible but clang raise these warnings:

test-sasl.c:555:13: error: variable 'is_ok' is uninitialized when used here [-Werror,-Wuninitialized]
        if (is_ok) {

        uint8_t is_ok;
                     ^
                      = '\0'

test-gst.c:792:18: error: variable 'height' is used uninitialized whenever '&&' condition is false [-Werror,-Wsometimes-uninitialized]
