[ndctl PATCH 08/10] cxl/list: Add support for filtering by host identifiers

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

Accept host device names as valid filters for memdevs, ports, and
endpoints.

# cxl list -u -m 7
{
  "memdev":"mem7",
  "pmem_size":"256.00 MiB (268.44 MB)",
  "ram_size":"256.00 MiB (268.44 MB)",
  "serial":"0x6",
  "numa_node":0,
  "host":"cxl_mem.6"
}

# cxl list -u -m cxl_mem.6
{
  "memdev":"mem7",
  "pmem_size":"256.00 MiB (268.44 MB)",
  "ram_size":"256.00 MiB (268.44 MB)",
  "serial":"0x6",
  "numa_node":0,
  "host":"cxl_mem.6"
}
