[PATCH] IPoIB: Set full membership bit in P_Keys

Browse source 
Always make sure that the full membership bit is set in the P_Keys
that IPoIB uses.  This makes sure that all hosts join the correct
multicast groups so that hosts that are partial partition members
can talk to the rest of the network.
