When one peer sends an infinite mapping to coordinate fallback from
MPTCP to regular TCP, the other peer is expected to send a packet with
the MPTCP MP_FAIL option to acknowledge the infinite mapping. Rather
than leave the connection in some half-fallback state, this series adds
a timeout after which the infinite mapping sender will reset the
connection.

Patch 1 adds a fallback self test.

Patches 2-5 make use of the MPTCP socket's retransmit timer to reset the
MPTCP connection if no MP_FAIL was received.

Patches 6 and 7 extends the self test to check MP_FAIL-related MIBs.

  selftests: mptcp: add infinite map testcase
  mptcp: use mptcp_stop_timer
  mptcp: add data lock for sk timers
  mptcp: add MP_FAIL response support
  mptcp: reset subflow when MP_FAIL doesn't respond
  selftests: mptcp: check MP_FAIL response mibs
  selftests: mptcp: print extra msg in chk_csum_nr
