Untangle unpinning from unlock/unref loop. The unpin only happens in error paths so it is easier to decouple from the normal unlock path. Since we never have an intermediate state where a subset of buffers are pinned (ie. we never bail out of the pin or unpin loops) we can replace the bo state flag bit with a global flag in the submit.
