Subject: [PATCH 3/3] arm64/numa: fix type info

numa_init(of_numa_init) may returned error because of numa configuration
error. So "No NUMA configuration found" is inaccurate. In fact, specific
configuration error information can be immediately printed by the
testing branch. So "No NUMA..." only needs to be printed when numa_off.
