[v5,05/14] arm64/numa: avoid inconsistent information to be printed

Commit Message

Leizhen (ThunderTown) Aug. 8, 2016, 9:18 a.m. UTC

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 should be immediately printed by the
testing branch.
