fbynite 11f2e9a491 vdev_ops: don't try to call vdev_op_hold or vdev_op_rele when NULL ... This prevents a panic after a SLOG add/removal on the root pool followed by a zpool scrub. When a SLOG is removed, a hole takes its place - the vdev_ops for a hole is vdev_hole_ops, which defines the handler functions of vdev_op_hold and vdev_op_rele as NULL. This bug has been reported in illumos and FreeBSD, a different trigger in the FreeBSD report though.
