ip4-input: fix prefetch data issue for tunnel decap cases
There are two reasons to modify the existing code ip4_input_inline. 1. For many tunnel decap cases, inner ip header or its part is possible in the second cacheline, not first cacheline only after the field "data", and this will cause data cache miss once the second cacheline is needed to access. e.g vxlan-gpe. 2. For most of cases, "data" is the starting address of ethernet header, not IP header. The existing code causes misunderstanding from code readability perspective.
