mptcp: pm: ADD_ADDR rtx: allow ID 0
ADD_ADDR can be sent for the ID 0, which corresponds to the local
address and port linked to the initial subflow.
Indeed, this address could be removed, and re-added later on, e.g. what
is done in the "delete re-add signal" MPTCP Join selftests. So no reason
to ignore it.
Fixes: 00cfd77b9063 ("mptcp: retransmit ADD_ADDR when timeout")
