btrfs-progs: defrag: force using v2 defrag ioctl and make default 32M threshold actually work

A user reported on IRC that the new 32M default for target extent size
does not work. This happens because if there are no commandline options,
the v1 ioctl is used that does not do any fine grained defrag. As the v2
ioctl has been introduced 6 years ago (2010, kernel 2.6.33) we won't
keep backward compatibility anymore.
