mptcp: misc fixes for v7.3-rc1

Here are various unrelated fixes:

- Patch 1: Do not reschedule the RTX timer for sockets that fell back to
  TCP. A fix for v5.7.

- Patch 2: Avoid copying thmac which will not be used and could be
  uninitialised. A fix for v5.7.

- Patch 3: Re-set the request backup flag when SYN cookies are used. A
  fix for v5.9.

- Patch 4: Drop pending ADD_ADDR when removing ID0, and avoid a WARN. A
  fix for v5.13.

- Patch 5: Handle invalid suboptions where the checksum is requested in
  the MP_CAPABLE 4th ACK with data, but not added in the option. A fix
  for v5.14.

- Patch 6: Prevent a race between mptcp_disconnect() and the retransmit
  timer. A fix for v5.17.

- Patch 7: Fix a use-after-free in the selftests that could lead to
  false positive. A fix for v5.17.

- Patch 8: Limit new addresses with the userspace PM to avoid an address
  ID overflow. A fix for v5.19.

- Patch 9: Reset the ADD_ADDR retransmission counter when the timer is
  reused. A fix for v5.19.

- Patch 10: Remove unneeded and confusing READ_ONCE() annotations. A fix
  for v6.13.

- Patches 11-12: Get nstat counters for the current test, not since the
  creation of the netns. A fix for v6.19.

- Patch 13: Fix an uninit-value in mptcp_write_data_fin for a corner
  case now that only a part of the tcp_out_options struct is reset. A
  fix for v7.1.

- Patches 14-15: Two follow-up patches addressing minor comments
  discovered after the human review. A fix for v7.3-rc1.
