[Piglit] [PATCH] ext_framebuffer_multisample: Add NORETURN attribute to print_usage_and_exit.

[Vinson Lee]

Silence clang sometimes-uninitialized warning.

accuracy.cpp:130:13: warning: variable 'test_type' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
        } else if (strcmp(argv[2], "depth_resolve") == 0) {
                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
accuracy.cpp:135:21: note: uninitialized use occurs here
        test = create_test(test_type, num_samples, small,
                           ^~~~~~~~~
accuracy.cpp:130:9: note: remove the 'if' if its condition is always true
        } else if (strcmp(argv[2], "depth_resolve") == 0) {
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
accuracy.cpp:119:2: note: variable 'test_type' is declared here
        test_type_enum test_type;
