libnvdimm, region: quiet region probe

djbw · djbw · commit 60ce0f936bda · 2018-04-07T07:47:10.000-07:00
The message about constraining number of online cpus to be less than or
equal to ND_MAX_LANES (256) is only useful for block-aperture
configurations and BTT. Make it debug since it is only relevant when
debugging performance.
