[ Upstream commit 492d9ec244923420af96db6b69ad7d575859aa92 ]

[why] We reset the optimized_required in atomic_plane_disable flag immediately after it is set in atomic_plane_disconnect, causing us to never have flag set during next flip in UpdatePlanes.

[how] Optimize directly after each time plane is removed.
