If a certain mcast group has only one member, and this
member is a switch, OSM fails to select this switch
when trying to create spanning tree for this mcast group:
ERR 0A08: Unable to locate a suitable switch for group 0xC000
ERR 0A17: Unable to create spanning tree (IB_ERROR) for mlid 0xc000

V2: no need to handle the case with no
members in mcast group, it is already
handled by the caller function.
