i965/fs: Use a default Y coordinate of 0 for TXF on gen9+
Previously, we were incrementing length but not actually putting anything
in the Y coordinate. This meant that 1-D TXF operations had a garbage
array index. If the surface is emitted as 1-D non-array, the coordinate
gets discarded and it works fine. If it happens to be bound as an array
surface, it may count as an out-of-bounds array access and you get zero.
