RDMA/cma: Initialize ib_sa_multicast structure to 0 when join
Initialize the structure to 0 so that it's fields won't have random
values. For example fields like rec.traffic_class (as well as
rec.flow_label and rec.sl) is used to generate the user AH through:
cma_iboe_join_multicast
cma_make_mc_event
ib_init_ah_from_mcmember
And a random traffic_class causes a random IP DSCP in RoCEv2.
