IB/core: Enable QP creation with a given source QP number
Enable QP creation with a given source QP number.
The created QP will use the source QPN as its wire QP number.
This comes as a pre-patch for downstream patches in this series to
allow user space applications to accelerate traffic which is typically
handled by IPoIB ULP.
