[Qemu-devel] [PATCH v3 10/13] block: Simplify bdrv_append_temp_snapshot() logic

[Eric Blake]

Noticed while checking Coccinelle results. Naming a label 'out:'
when it is only used on error paths is weird; meanwhile we know
that snapshot_options is NULL on success and that QDECREF(NULL)
is safe.  So merge the two exit paths into one.
