llvmpipe: fix race between draw and setting fragment shader.

There is a race with u_blitter shaders + pipeline shaders (aaline/aapoint)
where the draw bind can cause a pipeline flush which can use bind_fs_state to
 be reenters and llvmpipe->fs gets the wrong value. Fix this by only
setting the llvmpipe->fs value after the draw binding is complete.
