From: David Daney <david.daney@cavium.com>
As noted by Dennis Chen, we don't want to print "No NUMA configuration
found" if NUMA was forced off from the command line.
Change the type of numa_off to bool, and clean up printing code.
Print "NUMA disabled" if forced off on command line and "No NUMA
configuration found" if there was no firmware NUMA information.
