[PATCH v2 2/2] winex11.drv: Update _NET_WM_STATE before resizing windows.

[Zhiyi Zhang]

According to the Extended Window Manager Hints (EWMH) spec 1.3 regarding
_NET_WM_STATE_FULLSCREEN, "the Window Manager is responsible for
restoring the original geometry after a switch from fullscreen back to
normal window.", which means that removing _NET_WM_STATE_FULLSCREEN from
a window may cause the window to receive a ConfigureNotify event to
restore the window size, thus causing a application resize action to be
overwritten by the window managers.
