st/mesa: fix trimming of GL_QUAD_STRIP
We sometimes convert GL_QUAD_STRIP prims into GL_TRIANGLE_STRIP, but that changes the results of the u_trim_pipe_prim() call. We need to pass the original primitive type to the trim function. Note that OpenGL's GL_x prim type values match Gallium's PIPE_PRIM_x values. Fixes a failure in the new piglit degenerate-prims test. Note: This is a candidate for the stable branches.
