[libvirt] [PATCHv2] conf: return immediately on error in dhcp host element

[Laine Stump]

If an error was encountered parsing a dhcp host entry mac address or
name, parsing would continue and log a less descriptive error that
might make it more difficult to notice the true nature of the problem.

This patch returns immediately on logging the first error.
