fm10k: update xcast mode before synchronizing multicast addresses
When the PF receives a request to update a multicast address for the VF, it checks the enabled multicast mode first. Fix a bug where the VF tried to set a multicast address before requesting the required xcast mode. This ensures the multicast addresses are honored as long as the xcast mode was allowed.
