We are allocating backing using psbfb_alloc() and so
backing->stolen is always true. So we were freeing backing two times.
Moreover if we follow the execution path then we should be freeing
backing after we have released the helper. So remove the one which frees
backing before the helper is released.
While at it the error labels are also renamed to give a meaningful
name.

This patch was never picked up. It will not apply now.
Daniel, please let me know if you want me to resend after making
necessary changes.
I will pick this up and pass it along to Dave. Sorry for the delay.
This was not picked up. But I guess it is still true. Do you want me to
rebase and send it again..
