How will the qp_accesss_flags be implemented in a transport neutral 
way? If iWARP doesn't support the ib_access_flags values, a transport 
nuetral consumer can't pass them here.

Can we remove the need for a consumer to call rdma_cma_init_qp all 
together? Can we create a QP and move it to the init state when the 
consumer creates their rdma_cma_id?
