drm/i915: Remove delayed FBC activation.
The only time we should start FBC is when we have waited a vblank
after the atomic update. We've already forced a vblank wait by doing
wait_for_flip_done before intel_post_plane_update(), so we don't need
to wait a second time before enabling.
Removing the worker simplifies the code and removes possible race
conditions, like happening in 103167.
