btrfs: zoned: don't account data relocation space-info in statfs free space

Browse Source 
Don't account the free space in a data relocation space-info sub-group as
usable free space in statfs.

This is misleading as no user allocations can be made in this space-info
sub-group. It is only a target for relocation.
