[PATCH v3 0/4] sctp conntrack fixes

[Sriram Yagnaraman <sriram.yagnaraman@est.tech>]

A less diruptive change as opposed to below RFC patch:
https://lore.kernel.org/netfilter-devel/20230104113143.21769-1-sriram.yagnaraman@est.tech/

This contains a couple of bug fixes to existing bugs that were found
during the review of the above patch series, and also a patch that
unifies the ESTABLISHED states for primary and secondary paths.

Changes since v2:
- Remove UAPI changes for DATA_SENT since it is only part of 6.1-rc

Changes since v1:
- Reverted bff3d0534804: DATA_SENT state
- Set assured bit if new state is ESTABLISHED and direction is reply,
  regardless of the old state. Paths established by HEARTBEAT also gets
  the assured bit.
- Update nf_conntrack_sysctl documentation

  netfilter: conntrack: fix bug in for_each_sctp_chunk
