btrfs: zoned: zone finish data relocation BG with last IO

commit f84353c7 upstream.

For data block groups, we zone finish a zone (or, just deactivate it) when
seeing the last IO in btrfs_finish_ordered_io(). That is only called for
IOs using ZONE_APPEND, but we use a regular WRITE command for data
relocation IOs. Detect it and call btrfs_zone_finish_endio() properly.

Fixes: be1a1d7a ("btrfs: zoned: finish fully written block group")
