Fix taskq creation failure in vdev_open_children()
When creating and destroying pools in tight loop it's possible to
exhaust the number of allowed threads on a system. This results
in taskq_create() failling and a NULL dereference.
Resolve the issue by falling back to opening the vdevs all
synchronously.
