[libvirt] [PATCH 3/3] xenconfig: Resolve Coverity RESOURCE_LEAK

[John Ferlan]

Since '337a13628' - Coverity complains that 'net' is VIR_ALLOC()'d, but
on various 'cleanup' exit paths from the code there is no corresponding
cleanup.  Since 'net' is eventually appended onto a list of nets we don't
want to delete the last one - be sure to set it to NULL, but still call
the free function in cleanup
