lightningd: attach HTLC timeout to htlc itself, fix gratuitous disconnect bug.

Browse Source 
We set the timeout on first HTLC, but didn't clear it if that HTLC failed.

It's saner to have a per-HTLC timeout (since that's what it is!) and
also our timer infra is specially coded to scale approximately infinitely so
trying to optimize this is vastly premature.

Changelog-Fixed: Protocol: We would sometimes gratuitously disconnect 30 seconds after an HTLC failed.
