Allocate SR-IOV paravirtualization resources and MAD demuxing contexts on the master. This has two parts. The first part is to initialize the structures to contain the contexts. This is done at master startup time in mlx4_ib_init_sriov(). The second part is to actually create the tunneling resources required on the master to support a slave. This is performed the master detects that a slave has started up (MLX4_DEV_EVENT_SLAVE_INIT event generated when a slave initializes its comm channel). For the master, there is no such startup event, so it creates its own tunneling resources when it starts up. In addition, the master also creates the real special QPs. The ib_core layer on the master causes creation of proxy special QPs, since the master is also paravirtualized at the ib_core layer.
