vfs: Correct file_p variable usage within InterpretAsDirectory()

ReplaceFileWithSubdirectory() takes a VirtualFile and a VirtualDir, but
it was being passed a string as one of its arguments. The only reason
this never caused issues is because this template isn't instantiated
anywhere yet.

This corrects an issue before it occurs.
