net: Print hashed skb addresses for all net and qdisc events

The following commits added support for printing the real address-
65875073 ("net: use %px to print skb address in trace_netif_receive_skb")
70713ddd ("net_sched: introduce tracepoint trace_qdisc_enqueue()")
851f36e4

 ("net_sched: use %px to print skb address in trace_qdisc_dequeue()")

However, tracing the packet traversal shows a mix of hashes and real
addresses. Pasting a sample trace for reference-

ping-14249   [002] .....  3424.046612: netif_rx_entry: dev=lo napi_id=0x3 queue_mapping=0
skbaddr=00000000dcbed83e vlan_tagged=0 vlan_proto=0x0000 vlan_tci=0x0000 protocol=0x0800
ip_summed=0 hash=0x00000000 l4_hash=0 len=84 data_len=0 truesize=768 mac_header_valid=1
mac_header=-14 nr_frags=0 gso_size=0 gso_type=0x0
ping-14249   [002] .....  3424.046615: netif_rx: dev=lo skbaddr=ffffff888e5d1000 len=84

Switch the trace print formats to %p for all the events to have a
consistent format of printing the hashed addresses in all cases.
