Cygwin: fs_info::update: fix NTFS filesystem flags 

These flags are used to check a remote filesystem.  Not all
flags supported by a local NTFS are available when checking
a remote NTFS.  Fix the flag set accordingly, otherwise
the remote NTFS will ba handled as CIFS.

Fixes: fcccdc4021 ("Cygwin: fs_info: update filesystem flags and check Windows 7 flags")
