To activate RoCE/SRIOV, need to remove the following:
1. In mlx4_ib_add, need to remove the error return preventing
   initialization of a RoCE port under SRIOV.
2. In update_vport_qp_params (in resource_tracker.c) need to remove
   the error return when a RoCE RC or UD qp is detected.
   This error return causes the INIT-to-RTR qp transition to fail
   in the wrapper function under RoCE/SRIOV.
