When plane is detached from crtc in one atomic commit and then attached to another crtc in the next atomic commit, the second plane state swap will happen when the first commit is still running in the previous crtc's worker thread, which will result in two threads programming the same plane and run into undeterministic state. Fix is to add plane_mask check before state swap, together with crtc_mask check. This will make sure there is no pending worker thread working on the same plane.
