[Piglit] [PATCH] depthstencil-render-miplevels: Silence uninitialized variable warning.

[Vinson Lee]

This patch fixes this Clang sometimes-uninitialized warning.

depthstencil-render-miplevels.cpp:159:2: warning: variable 'format' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]
        default:
        ^~~~~~~
depthstencil-render-miplevels.cpp:163:16: note: uninitialized use occurs here
        GLenum type = format == GL_DEPTH_STENCIL
                      ^~~~~~
depthstencil-render-miplevels.cpp:141:15: note: initialize the variable 'format' to silence this warning
        GLenum format;
                     ^
                      = 0
