libnvdimm: write blk label set
After 'uuid', 'size', 'sector_size', and optionally 'alt_name' have been set to valid values the labels on the dimm can be updated. The difference with the pmem case is that blk namespaces are limited to one dimm and can cover discontiguous ranges in dpa space. Also, after allocating label slots, it is useful for userspace to know how many slots are left. Export this information in sysfs.
