[NTFS] - Fix POSIX rules. Fix accessing long filenames created in Windows when 8dot3 name creation is disabled.

Browse source 
Whether or not a filename should be interpreted as case-sensitive is dependent on a flag passed to the driver when a file is created (opened); it's separate from the namespace associated with the file being accessed.
