This reverts commit 2bed74b056. The host
authority functionality, though important, is less important than basic
stability. Exposing the game window during this period causes various
problems, since drawing the window runs game logic:
- On escape from the final level of a mission, the player escapes the mine
twice.
- The game window is freed prematurely during the cleanup after finishing the
mission. This later leads to a use-after-free while trying to return to the
main menu.
- Game sounds continue to play in the background while the kmatrix window is
open.
- There is a brief flash of a game after exiting the kmatrix window, before the
next level initializes completely and the player warps to the correct start
spot.
Remove the logic to expose the game window during this fragile time. If this
breaks the host authority code, that will need to be fixed differently.
Fixes: 2bed74b056 ("During kmatrix bring up Game_wind againso the host can still follow the game - becomes necessary later with host-authority functions")
