    rx: rxi_FindRpcStat must test for empty queue
    
    When queue_Scan is executed on an empty queue the queue element
    variable, in this case 'rpc_stat' is the queue head, _RXQ(q),
    and not NULL.  Callers of rxi_FindRpcStat() expect NULL on failure
    to find or create an rx_interface_stat object.  Correct the behavior
    by testing for an empty queue and return NULL immediately if the
    queue is empty and the caller is not requesting creation.
