When a failed probe comes along UNCONFIRMED path, it is not necessary

I do not find this in the RFC, but it seems reasonable - at least, I would
have liked to see a more elaborate commit message from you explaining why
it's okay to do; at least RFC6458 I read:
SCTP_ADDR_UNREACHABLE:
The address specified can no longer be reached. Any data sent
to this address is rerouted to an alternate until this address
becomes reachable. This notification is provided whenever an
address *becomes* unreachable.
Given that the transport has always been in state SCTP_UNCONFIRMED, it
therefore wasn't active before and hasn't been used before, and one could
argue that it doesn't "become" "unreachable" but always has been, so we
wouldn't need to bug the user with a notification about it.
