net: fix indirect calls helpers for ptype list hooks.

As Eric noted, the current wrapper for ptype func hook inside
__netif_receive_skb_list_ptype() has no chance of avoiding the indirect
call: we enter such code path only for protocols other than ipv4 and
ipv6.

Instead we can wrap the list_func invocation.

v1 -> v2:
 - use the correct fix tag
