verbs: Assign ibv srq->pd when creating SRQ

[ Upstream commit bf1e427 ]

Some providers need to access ibv_srq->pd during SRQ destruction, but
it may not be assigned currently when using ibv_create_srq_ex(). This
may lead to some SRQ-related resource leaks. Assign ibv_srq->pd when
creating SRQ to ensure pd can be obtained correctly.
