[igt-dev] [PATCH i-g-t] tests/kms_vrr: fix compilation with Clang

[Simon Ser <simon.ser@intel.com>]

Clang fails to compile this file with this error:

    ../tests/kms_vrr.c:203:20: error: suggest braces around
initialization of subobject [-Werror,-Wmissing-braces]
            drmVBlank vbl = { 0 };
                              ^
                              {}

As discussed in [1], using an empty initializer list is the preferred
way to fix this.
