patch to dlls/user32/winproc.c to prevent unhandled memory exception

Thi is a patch to dlls/user32/winproc.c that remaps the pointer data to the
client application after coming back from a callback for the WM_MDICREATE and
WM_CREATE messages of WINPROC_CallProc16To32A. Note that cs->lpszName and
cs->lpszClass (see CREATESTRUCT16to32A) are not remapped so they could create
problems somewhere int he callback (not for me though).
