drm/i915: Fix flushing regression from 9af90d19f
Whilst moving the code around in 9af90d19f, I dropped the or'ing in of new write domains which would zero out the write domain for a render target if later reused as a source later in the batch. This meant that we might drop a required flush before reading from the render target.
