softpipe: Fix softpipe_is_texture_referenced.
Render results are only visible when the render cache is flushed. softpipe_is_texture_referenced must reflect that or transfers to/from the textures bound in the framebuffer won't be proceeded of the necessary flush, causing transfer data to be outdated/clobbered. This fixes conform drawpix test with softpipe.
