drm/i915: don't reallocate the compressed FB at every frame
With the current code we just reallocate the compressed FB at every
FBC update: we have X in one frame, then in the other frame we need X
again, but we check "needed < have" instead of "needed <= have".
v2: Rebase after Jani addressed the other problems described in v1.
