btrfs-progs: fix a BUG_ON() condition for write_data_to_disk() 

The BUG_ON() condition in write_data_to_disk() is no longer correct.

Now write_raid56_with_parity() will return the bytes written of last
stripe.

Thus a success writeback can trigger the BUG_ON(ret).

Fix the condition to (ret < 0).
