Remove unnecessary null pointer checks

[elfring]

An extra null pointer check is not needed in functions like the following.

• LdrModule_CloseHandleModule
• VfsClose

Thanks for making me aware of this. I imagine there are quite a few places in the code.

I'll remove this in my internal dev version and push the changes in my next release which will hopefully contain some new features as well. It's always nice to simplify the code a bit.

I'm closing this issue since this has been resolved in Version 1.1 published a week ago.

Thanks for your source code improvement.
