[PATCH] network_conf: Don't free uninitialized pointers while parsing DNS SRV

[Peter Krempa <pkrempa@xxxxxxxxxx>]

If the user specified invalid protocol type in a network's SRV record
the error path ended up in freeing uninitialized pointers causing a
daemon crash.

*network_conf.c: virNetworkDNSSrvDefParseXML(): initialize local
                                                variables
