[eoib] Allow the multicast group to be forcefully created

Browse Source 
Some EoIB implementations require each individual EoIB node to create
the multicast group for the EoIB broadcast domain.

It is left as an exercise for the interested reader to determine how
such an implementation might ever allow the parameters of such a
multicast group to be changed without requiring a simultaneous upgrade
of every driver on every operating system on every machine currently
attached to the fabric.
