From: Kaike Wan <kaike.wan@xxxxxxxxx>
When an old ack_queue entry is used to store an incoming request,
it may need to clean up the old entry if it is still referencing
the mr. Originally only RDMA READ request needed to reference
mr on the responder side and therefore the opcode was tested when
cleaning up the old entry. The introduction of tid rdma specific
operations in the ack_queue makes the specific opcode tests wrong.
Multiple opcodes (RDMA READ, TID RDMA READ, and TID RDMA WRITE) may
need mr ref cleanup.
Remove the opcode specific tests associated with the ack_queue.
