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
Fixes: f5737cbadb7d ("net: use indirect calls helpers for ptype hook")
