i965: Mark the render target as dirty within composite_setup() 

The key difference between i965 and earlier, is that the surfaces passed
to the samplers through an indirect table and so the batch and render
target was not being marked dirty by the relocation (since the
relocation only happens within prepare_composite() which may have been
in another batch.) Simply call intel_pixmap_mark_dirty() when binding
the sampler table into the batch to ensure that the dirty is tracked
appropriately.
