libnvdimm, btt: consolidate arena validation
Use arena_is_valid as a common routine for checking the validity of an info block from both discover_arenas, and nd_btt_probe. As a result, don't check for validity of the BTT's UUID, and lbasize. The checksum in the BTT info block guarantees self-consistency, and when we're called from nd_btt_probe, we don't have a valid uuid or lbasize available to check against. Also cleanup to return a bool instead of an int. Signed-off-by: Vishal Verma <vishal.l.verma@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
