[ndctl PATCH 3/4] ndctl, list: fix span for btt badblocks check

[Dan Williams <dan.j.williams@intel.com>]

The size returned by ndctl_btt_get_size() accounts for space consumed by
metadata or otherwise lost to sector size geometry. For the
'badblock_count' property all we can do is report a count of possible
badblocks which may be larger than actual badblocks impacting live data.
Use the raw namespace size for this check.
