IB/mlx4: Create paravirt contexts for VFs when master IB driver initializes
When we have VFs and PFs on same host, the VFs are activated within the mlx4_core module before the mlx4_ib kernel module is loaded. When the mlx4_ib module initializes the PF (master), it now creates MAD paravirtualization contexts for any VFs that already active.
