markj 3579270d7e Avoid dropping the topology lock in gmirror's dumpconf implementation. ...

Doing so introduces races which can lead to a use-after-free when

To ensure that a mirror's disk list remains stable, change its locking
protocol: both the softc lock and the topology lock are now required
to modify the list, so either lock is sufficient for traversal.
