btrfs: zoned: clone zoned device info when cloning a device
When cloning a btrfs_device, we're not cloning the associated
btrfs_zoned_device_info structure of the device in case of a zoned
filesystem.
Later on this leads to a NULL pointer dereference when accessing the
device's zone_info for instance when setting a zone as active.
This was uncovered by fstests' testcase btrfs/161.
