Improve error reporting when parsing dhcp info for virtual networks
This is partially in response to https://bugzilla.redhat.com/show_bug.cgi?id=653300 The crash in that report was coincidentally fixed when we switched from using inet_pton() to using virSocketParseAddr(), but the absence of an ip address in a dhcp static host definition was still silently ignored (and that entry discarded from the saved XML). This patch turns that into a logged failure; likewise if the entry has neither a mac address nor a name attribute (the entry is useless without at least one of those, plus an ip address). Since the network name is now pulled into this function in order for those error logs to be more informative, the other error messages in the function have also been changed to take advantage.
