ntfs: Use new syncing helpers and update comments
Use new syncing helpers in .write and .aio_write functions. Also remove superfluous syncing in ntfs_file_buffered_write() and update comments about generic_osync_inode(). CC: Anton Altaparmakov <aia21@cantab.net> CC: linux-ntfs-dev@lists.sourceforge.net Signed-off-by: Jan Kara <jack@suse.cz>
