Before commit 297e0da (IB/mlx4: Handle Ethernet L2 parameters for IP based GID
addressing) local variable 'is_mcast' in function create_iboe_ah() was
guaranteed to be set after calling mlx4_ib_resolve_grh(). Since 297e0da
'is_mcast' is set in case of rdma_is_multicast_addr(), but otherwise left
uninitialized. Thus init 'is_mcast' to 0. Detected by Coverity - CID 1164324
