Hm, using a kernel address (drop_reasons) as an argument to TP_printk()
definitely does not look right, but how to tickle whatever magic
__print_symbolic was providing I do not know :S

 	TP_printk("skbaddr=%p protocol=%u location=%p reason: %s",
 		  __entry->skbaddr, __entry->protocol, __entry->location,
-		  __print_symbolic(__entry->reason,
-				   TRACE_SKB_DROP_REASON))
+		  drop_reasons[__entry->reason])
