ntfs3: pretend $Extend records as regular files

Browse Source 
[ Upstream commit 4e8011ffec79717e5fdac43a7e79faf811a384b7 ]

Since commit af153bb63a33 ("vfs: catch invalid modes in may_open()")
requires any inode be one of S_IFDIR/S_IFLNK/S_IFREG/S_IFCHR/S_IFBLK/
S_IFIFO/S_IFSOCK type, use S_IFREG for $Extend records.
