ice: Avoid detrimental cleanup for bond during interface stop

ice: Avoid detrimental cleanup for bond during interface stop

When the user issues an administrative down to an interface that is the
primary for an aggregate bond, the prune lists are being purged. This
breaks communication to the secondary interface, which shares a prune
list on the main switch block while bonded together.

For the primary interface of an aggregate, avoid deleting these prune
lists during stop, and since they are hardcoded to specific values for
the default vlan and QinQ vlans, the attempt to re-add them during the
up phase will quietly fail without any additional problem.
