IB/ipoib: Update broadcast object if PKey value was changed in index 0
Update the broadcast address in the priv->broadcast object when the Pkey value changes in index 0, otherwise the multicast GID value will keep the previous value of the PKey, and will not be updated. This leads to interface state down because the interface will keep the old PKey value. For example, in SR-IOV environment, if the PF changes the value of PKey index 0 for one of the VFs, then the VF receives PKey change event that triggers heavy flush. This flush calls update_parent_pkey that update the broadcast object and its relevant members. If in this case the multicast GID will not be updated, the interface state will be down.
