Long hostnames result in qubesdb paths that exceed the current 64 character limit. Instead of crashing the firewall daemon, log the error and continue without adding the hostname to the DNS records. This is a workaround, not a fix, for https://github.com/QubesOS/qubes-issues/9084. The fix requires either longer path support in qubesdb or using a different schema so that keys will not exceed the qubesdb path length limit.
