i965: Delete brw_sf_state.c again

"...and stay dead!"

Rafael deleted this file in c2b5a26dc25b9c62954a75465e25294c7fd3851a
(i965: Convert SF_STATE to genxml.) but Marek accidentally brought it
back in commit e7a091936fb6fd578c6ced9baa38b306b638a11b (mesa: replace
ctx->Polygon._FrontBit with a helper function) when resolving conflicts.

It's not actually even compiled, but it's still here trolling people
into thinking it still exists and needs patching.
