Patch 1: extends the RDMA LIF identity with SRQ qtype and alloc_qid_cap. Patch 2: uses that for firmware-assigned CQ IDs and splits CQ create/destroy so cq_tbl is updated only after the ID is known, and removed before the ID is returned to firmware. Patches 3: Refactor RQ state into ionic_rq so QP RQ and SRQ share init/destroy. Patches 4-5: add SRQ verbs and EQ events.
