[PATCH] ntdll: Catch EXCEPTION_INVALID_HANDLE in NtClose.

[Rémi Bernon]

That was dropped in 4752e252ea6ee084b679a9b9551a1c55f8744451 and it
causes Metal Gear Solid V: Ground Zeroes to crash on start. The game
debugs itself and closes an invalid handle as an anti-debug check.

I'm not sure why the try catch was removed, and maybe there's a better
fix to it?
