When in HA mode, the driver exposes an IB (RoCE) device instance with only
one port. Under SRIOV, the existing implementation doesn't go well with
the PF RoCE driver's role of Special QPs Para-Virtualization and such.
As such, disable HA for the mlx4 PF RoCE device in SRIOV mode.
Fixes: a57500903093 ('IB/mlx4: Add port aggregation support')
