zed: post a udev change event from spa_vdev_attach()

In order for zed to process the removal event correctly,
udev change event needs to be posted to sync the blkid
information. spa_create() and spa_config_update() posts
the event already through spa_write_cachefile(). Doing
the same for spa_vdev_attach() that handles the case
for vdev attachment and replacement.
