SubjectRe: Problem in pfmemalloc skb handling in net/core/dev.c

It seems "sk_filter_trim_cap" needs an "struct sock" argument. Some of
my protocols act like a middle layer to another protocol and don't
have any "struct sock".

Also, I think this is a problem in net/core/dev.c, there are a lot of
old protocols that are not aware of pfmemalloc skbs. I don't think
it's a good idea to fix them one by one.
