RDMA/ucma: Allow user space to specify AF_IB when joining multicast
Allow user space applications to join multicast groups using MGIDs
directly. MGIDs may be passed using AF_IB addresses. Since the
current multicast join command only supports addresses as large as
sockaddr_in6, define a new structure for joining addresses specified
using sockaddr_ib.
Since AF_IB allows the user to specify the qkey when resolving a
remote UD QP address, when joining the multicast group use the qkey
value, if one has been assigned.
