In the current xprtrdma implementation, some memreg strategies implement ro_unmap synchronously (the MR is knocked down before the method returns) and some asynchonously (the MR will be knocked down and returned to the pool in the background). To guarantee the MR is truly invalid before the RPC consumer is allowed to resume execution, we need an unmap method that is always synchronous, invoked from the RPC/RDMA reply handler. The new method unmaps all MRs for an RPC. The existing ro_unmap method unmaps only one MR at a time.
