drm/i915: fix order of fence release wrt flushing
i915_gem_object_unbind had the ordering wrong. The other user,
i915_gem_object_put_fence_reg already has the correct ordering.
Results was usually corrupted pixmaps, especially garbled font glyphs
after a suspend/resume (because this evicts everything).
I'm still waiting for the feedback from the bug-reporters, but
because this obviously fixes a bug (at least for me) I'm already
submitting it.
