[PATCH v2] ntdll: Fix overflow if running 32bit app w/ wine64

[Brendan McGrath]

I ran this test with WINEDEBUG=+relay with and without the patch.

With the patch I see this entry:
0067:Call PE DLL (proc=0x7fe6ef3a8610,module=0x7fe6ef380000 
L"mscoree.dll",reason=PROCESS_ATTACH,res=0x22fb00)

Without the patch I don't (in fact the text 'mscoree' isn't in the log 
at all).

So I think the crash happens before the mscoree.dll library is loaded. 
And I guess this makes sense since the issue is with allocation of 
memory for the stack of the main process.
