fix: Uber block label not always found for aux vdevs
When spare or l2cache (aux) vdev is added during pool creation, spa->spa_uberblock is not dumped until that point. Subsequently, the aux label is never synchronized after its initial creation, resulting in the uberblock label remaining undumped. The uberblock is crucial for lib_blkid in identifying the ZFS partition type. To address this issue, we now ensure sync of the uberblock label once if it's not dumped initially.
