[Mesa-dev] [PATCH 06/11] i965/fs: Drop the viewport index/rtai clearing in gen6 fb writes.

[Eric Anholt]

These fields are documented to be in the payload, and though the FB
write docs say they *aren't* in the payload, for all other fields the
payload and header is structured so that no overwriting is required
except for non-default options.
