https://github.com/multipath-tcp/mptcp_net-next/issues/97

To fix the above, MPTCP needs to be able to cope with memory allocation
failure in do_tcp_sendpages().

In this iteration the patches are rebased on top of:

"bpf:selftests: add bpf_mptcp_sock() verifier tests"

and should apply without fuzz on net-next.

patch 1/2 went through some lifting to be hopefully more acceptable
upstream.

This will cause a few conflicts in later patch, specifically in
"mptcp: move page frag allocation in mptcp_sendmsg()". Possibly the
simpler/better would be squashing 2/2 in there.

The plan is to send 1/2 and "tcp: factor out __tcp_close() helper"
as RFC upstream soon/while net-next is closed to try to understand
if that could be acceptable. The 2 TCP patches alone, without the full
series to hopefully make the review simpler/less cumbersome.

Any feedback more than welcome!!!
