ANDROID: net: export symbol for tracepoint_consume_skb

Browse Source 
Need to use the tracepoint_consume_skb symbol at module driver
This used on our vendor hook, the android_vh_ptype_head.
It's a debugging feature to trace packet flow when skb is freed.

We just traced at kfree_skb only before,
But we need tracing skb at consume_skb too, for analyze to more complex mobile network issues.
