When rxrpc_recvmsg_data() gets called on a service call that has received
all of the request, RXRPC_CALL_RECVMSG_READ_ALL has been set, and this
causes rxrpc_recvmsg_data() to jump straight out, indicating the end of the
call (ie. rxrpc_kernel_recv_data() returns 1) without waiting for the call
to be processed or the reply to be transmitted.
rxperf_deliver_to_call() also has to be altered to call
rxrpc_kernel_recv_data() to collect the final ACK on a service call as does
afs_deliver_to_call().
Fixes: d001648ec7 ("rxrpc: Don't expose skbs to in-kernel users [ver #2]")
