Noticed while checking Coccinelle results. Naming a label 'out:'
when it is only used on error paths is weird. Also, we had some
dead stores to 'ret'. Meanwhile we know that snapshot_options
is NULL on success and that QDECREF(NULL) is safe. So merge the
two exit paths into one by careful control over bs_snapshot.
