[PATCH 2/2] wined3d: Update the swapchain windows' sizes after it has been unminimized.

[Gabriel Ivăncescu]

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. The behavior is correct wrt Windows, but some games
expect the window pos change messages to be sent while they are unminimized,
but we only sent it during the WM_ACTIVATEAPP hook.
