[USER32_APITEST] Disable WndProc test when runtime checks are enabled [KERNEL32_WINETEST] Zero initialize a buffer. This is necessary, since we fail all calls to GetVolumePathNamesForVolumeNameW and thus never get any data into the buffer, which can later result in a buffer-overrun, when doing a lstrlenW on it. svn path=/trunk/; revision=64831
