Be consistent, and even when we know we had used a WC, flush the mapped object after writing into it. The flush understands the mapping type and will only clflush if !I915_MAP_WC, but will always insert a wmb [sfence] so that we can be sure that all writes are visible. v2: Add the unconditional wmb so we are know that we always flush the writes to memory/HW at that point.
