domain_conf.c: remove 'error' label in virDomainDefTunablesParse()

Browse Source 
The 'error' label is just doing a 'return -1'.

There's also a couple of 'VIR_FREE(nodes)' calls that are happening
right before exiting on error, but 'nodes' is already set for
autocleanup. These calls can also be removed.
