[PATCH rdma-next 1/6] IB/core: Enable QP creation which is associated to underlay QP

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Yishai Hadas <yishaih-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Enable QP creation which is associated to underlay QP.
The created QP will manage the scattering objects as of RQ and SQ, while
the transport attributes will be managed by its underlay QP

This comes as a pre-patch for downstream patches in this series to
enable flow steering on the underlay IPoIB QP.
