virtio-blk: Fix zone append sector reporting in batched completion

For zone append, the block layer copies req->__sector back into the
bio in blk_zone_append_update_request_bio(), so the driver must update
req->__sector with the sector reported by the device.
virtblk_request_done() does that, but the batched completion path used
by virtblk_poll() only unmaps and cleans up the requests before calling
blk_mq_end_request_batch().

A zone append completed through polling therefore keeps the sector that
was assigned at submission time, and the file system or application sees
the wrong LBA for the written data.

Move the sector update into a helper and call it from both completion
paths.
