Subject: [PATCH] ntdll-Zero_mod_name: Remove patch.

After examining the code several times I'm convinced that, according to the C
specification, it shouldn't have any effect.

That said, it's supposed to be for Cygwin, and bug 47812 describes a rather
insane thing that Cygwin does with the stack. If Cygwin is accessing overwritten
stack memory, then it seems reasonable that something like this patch set has an
effect.

Bug 47812 is fixed now, though, so let's remove this patch.
