[M60] exo: Fix cursor scale when crossing displays

While dragging, the cursor was locked, so CursorClient::SetCursor calls
were collapsed into a single call at the end of the drag. When crossing
displays with different densities, the cursor scale was incorrect until
the window was dropped. This CL removes cursor locking to prevent the
OnCursorDisplayChanged update from being postponed.
