commit 173431b274a9a54fc10b273b46e67f46bcf62d2e upstream.
Add extra sanity check for btrfs_ioctl_defrag_range_args::flags.
This is not really to enhance fuzzing tests, but as a preparation for
future expansion on btrfs_ioctl_defrag_range_args.
In the future we're going to add new members, allowing more fine tuning
for btrfs defrag. Without the -ENONOTSUPP error, there would be no way
to detect if the kernel supports those new defrag features.
