[Intel-gfx] [PATCH 23/25] drm/i915/fbc: call intel_fbc_pre_update earlier during page flips

[Paulo Zanoni]

Make sure we do the pre_update - which also deactivates FBC - before
we actually schedule the page flip, just to make sure we don't
flip to the new FB with FBC still activated for the previous FB.
