ldlinux: workaround for avoiding EDD error on btrfs probe

When installing Syslinux in an NTFS volume and then booting it up,
Syslinux will print on the screen an EDD error ocurred on btrfs probing
because that volume is not actually a btrfs one. Thus, to work around
that issue add ntfs_fs_ops structure just before the btrfs_fs_ops so
that fs_init() function will execute the ntfs_fs_ops->fs_init() function
first, and on success, btrfs_fs_ops->fs_init() won't be executed either.

6;  A program to boot Linux kernels off an MS-DOS formatted floppy disk.  This

10;  This program allows manipulation of the disk to take place entirely
11;  from MS-LOSS, and can be especially useful in conjunction with the
12;  umsdos filesystem.
