be2net: disable RSS when number of RXQs is reduced to 1 via set-channels
When *only* the default RXQ is used, the RSS policy must be disabled so
that all IP and no-IP traffic is placed into the default RXQ. If not,
IP traffic is dropped.
Also, issue the RSS_CONFIG cmd only if FW advertises RSS capability for
the interface.
