swrast: Don't do Z24S8 drawpixels fast-paths with Z32_X24S8 input data.

The cool part was that in the "fbo-depthstencil -drawpixels
GL_DEPTH24_STENCIL8 32F_24_8_REV" testcase, the shifting happened to
end up with a value awfully close to the expected value, except for
every other pixel being 0 (the stencil value, shifted away to
nothing).
