Update vdev state for spare vdev 

zfsd fetches new pool configuration through ZFS_IOC_POOL_STATS but
it does not get updated nvlist configuration for spare vdev since
the configuration is read by spa_spares->sav_config. In this commit,
updating the vdev state for spare vdev that is consumed by zfsd on
spare disk hotplug.
