i965: Apply post-sync non-zero workaround to homebrew workaround.
In commit 3e5d3626, Eric added a homebrew workaround to fix GPU hangs in
the Mesa "engine" demo and oglc's api-texcoord test.
Unfortunately, his PIPE_CONTROL contains a Depth Stall, which
necessitates the post-sync non-zero workaround,
Fixes GPU hangs in Civilization 4, PlaneShift, Minecraft, Neverwinter
Nights, 3DMMES, and hopefully Heroes of Newerth as well.
