PATCH: findclose exception

[Marcus Meissner <marcus@jet.franken.de>]

Hi,

The Zak McKracken 2 Demo Installer crashes with FindClose(0xfffffffe). 
Since we already handle 0xffffffff and there is a page fault handler in
this function already, I just extend it to contain all critical parts.

Ciao, Marcus

	FindClose: protect the GlobalLock for pagefaults too.
