Fixes a regression introduced by commit 82c6ec3a32f44e8b3e0cc88b7f10e0c0d7fa1b89, which caused the WM_ACTIVATEAPP to be sent while the window is minimized, if it has been clicked on in the taskbar to be restored.
According to the Extended Window Manager Hints spec, WMs remove the NET_WM_STATE_FULLSCREEN state when restored, they use the previous size of the window (not the fullscreen). This caused the WM_SYSCOMMAND SC_RESTORE message's ShowWindow to revert the window back to its original (non-fullscreen) size, instead of being restored to fullscreen, breaking some apps like Heroes of Might and Magic V.
We have to override the X server's window state here to match Windows behavior and restore it back to fullscreen.

read_net_wm_states is when X11 changes some state from outside Wine and sends it a notification that it did; then Wine has to update its own wm states to match the X server (so it's properly integrated).
However, in this case, since the WM clears the fullscreen state on minimization, we must not do that, because Windows doesn't—and more, when the window is restored from minimized, we must ignore the X11 state changes and force it back to what Wine had (usually fullscreen unless it gets hooked by the app, then we keep what the app changed, which is fine). This is to match Windows behavior, which differs from X11, and apps rely on.
