Subject: kernel/trace/bpf_trace.c: work around gcc-4.4.4 anon union
 initialization bug

kernel/trace/bpf_trace.c: In function 'bpf_event_output':
kernel/trace/bpf_trace.c:312: error: unknown field 'next' specified in initializer
kernel/trace/bpf_trace.c:312: warning: missing braces around initializer
kernel/trace/bpf_trace.c:312: warning: (near initialization for 'raw.frag.<anonymous>')

Fixes: 555c8a8623a3a87 ("bpf: avoid stack copy and use skb ctx for event output")
