btrfs: remove the zoned/zone_size union in struct btrfs_fs_info

Reading a value from a different member of a union is not just a great
way to obfuscate code, but also creates an aliasing violation.  Switch
btrfs_is_zoned to look at ->zone_size and remove the union.

Note: union was to simplify the detection of zoned filesystem but now
this is wrapped behind btrfs_is_zoned so we can drop the union.
