Chris Wilson 1a74934b0e drm/i915/gem: Flush the pwrite through the chipset before signaling
Before we signal the fence to indicate completion, ensure the pwrite
through the indirect GGTT is coherent (as best as we know) in memory.
Any listeners to the fence may start immediately and sample from the
backing store prior to the writes being posted, thus seeing stale data.
