[ Upstream commit 4fc68c4c1a114ba597b4f3b082f04622dfa0e0f6 ]
Fix rxrpc_cleanup_ring() to use rxrpc_purge_queue() rather than skb_queue_purge() so that the count of outstanding skbuffs is correctly updated when a failed call is cleaned up.
Without this rmmod may hang waiting for rxrpc_n_rx_skbs to become zero.
