domain_conf.c: modernize virDomainDefControllersParse()

The 'error' label is just returning -1, so let's 'return -1'
directly.

Use g_autoptr() with virDomainControllerDefPtr to remove the
need to call virDomainControllerDefFree() in the error path.

There is no need to VIR_FREE(nodes) explictly since 'nodes'
is using g_autofree.
