st/mesa: fix glReadBuffer() assertion failure
If the first call in a GL app is glReadPixels(GL_FRONT) we'd fail the assert(st->ctx->FragmentProgram._Current) at st_atom_shader.c:114 in update_fp(). This is because we were calling st_validate_state() without first updating Mesa state with _mesa_update_state(). The regression came from commit 83b589301f4a150f4 "st/mesa: fix frontbuffer glReadPixels regressions". The new piglit gl-1.0-simple-readbuffer test exercises this.
