Alan Somers cbedc01c9a Fix race condition involving ZFS remove events ... When a ZFS drive disappears, ZFS sends a resource.fs.zfs.removed event to userland. A userland program like zfsd(8) can use that event, for example to activate a hotspare. The current code contains a race condition: vdev_geom will sent the sysevent _before_ spa.c would update the vdev's status, causing userland processes to see pool state that does not reflect the device removal. This change moves the sysevent to spa.c, closing the race.
