Paolo Abeni 7d6e8d7ee1 mptcp: fix lockless access in subflow ULP diag
commit b8adb69a7d29c2d33eb327bca66476fb6066516b upstream.

Since the introduction of the subflow ULP diag interface, the
dump callback accessed all the subflow data with lockless.

We need either to annotate all the read and write operation accordingly,
or acquire the subflow socket lock. Let's do latter, even if slower, to
avoid a diffstat havoc.

Fixes: 5147dfb508 ("mptcp: allow dumping subflow context to userspace")
