[PATCH] Error in PE Loader relocations (LdrPerformRelocations)

In LdrPerformRelocations(), on line 01408, there's an error in calculating the Delta when performing relocations:

Delta = (ULONG_PTR)ImageBase - NTHeaders->OptionalHeader.ImageBase;

The problem is that the NTHeaders->OptionalHeader.ImageBase variable may be greater than the ImageBase variable, thus, if the smaller is subtracted from the larger, will create a negative number, resulting in incorrectly relocated code.

The fix I thought up would end up looking something like this:

Delta = max((ULONG_PTR)ImageBase, NTHeaders->OptionalHeader.ImageBase) - min((ULONG_PTR)ImageBase, NTHeaders->OptionalHeader.ImageBase);

Thanks!
