RDMA/mana_ib: Revise UD receive posting with GDMA_WR_IB_SGL
Decouple RQ WQE posting from the QP structure so it can be reused by
other QP types. Batch multiple receive WQEs under a single doorbell.
Introduce GDMA_WR_IB_SGL to pass SGEs directly to GDMA instead of copying
them into a small stack array. Support receive WQEs with num_sge set to
zero.
