Process parent is `None` if the target process of `refresh_process_specifics()` is a WoW64 process #1313

If the target process is a WoW64 process, NtQueryInformationProcess(ProcessBasicInformation) is skipped and process.parent is not set. However, NtQueryInformationProcess(ProcessBasicInformation) actually works fine for WoW64 processes, at least for the InheritedFromUniqueProcessId part.

Simply moving this NtQueryInformationProcess out of the if guard seems to solve the problem. If needed, I can make a PR for this change.
