This reverts the patch: when add_addr_timeout is set to 1, chk_add_nr()
and chk_add_tx_nr() are more tolerant with retransmissions, see commit
6ef84b1517e0 ("selftests: mptcp: more robust signal race test").
But the main reason is that this revert breaks the selftests running on
old kernels.
It is then important to keep this. Plus it still acts as a maximum, just
in case everything is very slow, we still have retransmissions in time,
especially with the new exponential backoff.
