btrfs: disable balance for extent tree v2 for now
With global root id's it makes it problematic to do backref lookups for
balance. This isn't hard to deal with, but future changes are going to
make it impossible to lookup backrefs on any COWonly roots, so go ahead
and disable balance for now on extent tree v2 until we can add balance
support back in future patches.
