Merge branch 'net-lockless-skb_attempt_defer_free'

Eric Dumazet says:

====================
net: lockless skb_attempt_defer_free()

Platforms with many cpus and relatively slow inter connect show
a significant spinlock contention in skb_attempt_defer_free().

This series refactors this infrastructure to be NUMA aware,
and lockless.

Tested on various platforms, including AMD Zen 2/3/4
and Intel Granite Rapids, showing significant cost reductions
under network stress (more than 20 Mpps).
