Merge branch 'net-sched-refine-fq_codel-memory-limits'

Eric Dumazet says:

====================
net/sched: refine fq_codel memory limits

Packets that are associated with local sockets sk_wmem_alloc
do not really need additional memory control.

First patch makes is_skb_wmem() available to modules.

Second patch uses is_skb_wmem() in fq_codel.
