btrfs: remove unreachable return after btrfs_backref_panic() in btrfs_backref_finish_upper_links()

The return statement after btrfs_backref_panic() is unreachable since
btrfs_backref_panic() calls BUG() which never returns. Remove the
return to unify it with the other calls to btrfs_backref_panic().
