send_update() does not retry if provider setup fails

[mhkrebs]

I'm running Inadyn on Home Assistant. I have two hostnames configured to update for cloudflare.

I noticed that the first IP address never updated, and here are the [redacted] logs:

2025-03-02T11:30:55.003997000Z inadyn[142]: Failed connecting to 1.1.1.1: Operation in progress

2025-03-02T11:33:36.606211000Z inadyn[142]: Updating IPv4 cache for sub2.domain2.com

I'm guessing there was some networking issue, and it had trouble getting the IP address until T11:31:15.391074000Z. At that point it called send_update() to set the IP address for "sub1.domain1.com".

I believe the problem is that cloudflare's info->system->setup function then failed, but there's no retry in that case:

inadyn/src/ddns.c

Lines 617 to 618 in d809e2b

	if (info->system->setup)
	DO(info->system->setup(ctx, info, alias));

All but one of the other failure cases in that function set alias->force_addr_update = 1 to presumably retry later.

Can that call to the provider setup function also set force_addr_update if it fails?

(FYI, the IP address for "sub2.domain2.com" did update as expected then.)
