tipc: eliminate duplicated discard_rx_queue routine
The tipc function discard_rx_queue() is just a duplicated implementation of __skb_queue_purge(). Remove the former and directly invoke __skb_queue_purge(). In doing so, the underscores convey to the code reader, more information about the current locking state that is assumed.
