net/sched: fq_codel: local packets no longer count against memory limit

Browse Source 
Commit 95b58430ab ("fq_codel: add memory limitation per queue")
claimed that the 32Mb default was "reasonable even for heavy duty usages."

In practice, this is not the case.

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