tcp: remove sk_{tr}x_skb_cache
This reverts the following patches : - commit 2e05fcae ("tcp: fix compile error if !CONFIG_SYSCTL") - commit 4f661542 ("tcp: fix zerocopy and notsent_lowat issues") - commit 472c2e07 ("tcp: add one skb cache for tx") - commit 8b27dae5 ("tcp: add one skb cache for rx") Having a cache of one skb (in each direction) per TCP socket is fragile, since it can cause a significant increase of memory needs, and not good enough for high speed flows anyway where more than one skb is needed. We want instead to add a generic infrastructure, with more flexible per-cpu caches, for alien NUMA nodes.
