[Mesa-dev] [PATCH 3/9] i965: move update_xfb_info() call out of loop

[Timothy Arceri]

We can just call it once. Also a following patch will also introduce
link time component packing which modifies the outputs_written
bit mask, we want to avoid calling update_xfb_info() until after
packing is completed.
