[Piglit] [PATCH] arb_uniform_buffer_object-maxblocks: Silence uninitialized variable warning.

[Vinson Lee]

This patch fixes this Clang sometimes-uninitialized warning.

maxblocks.c:117:2: warning: variable 'shader' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]
        default:
        ^~~~~~~
maxblocks.c:124:9: note: uninitialized use occurs here
        return shader;
               ^~~~~~
maxblocks.c:62:14: note: initialize the variable 'shader' to silence this warning
        char *shader;
                    ^
                     = NULL
