Looks like "geom disk status" and "geom disk list"
both list "disks" that do not have a partition scheme
and spans the nvd* disks. (I only tested destroying a
partition scheme on an ada* and then seeing what
was displayed. I do not want to destroy such on any
nvd* as stands.)

"geom disk list" shows Mediasize and descr, which
at times could be handy for identification, at
least when the pair are unique in the system.

Thanks for the alternatives to sysctl kern.disks
and to nvmecontrol devlist for making a list to
compare to gpart show output in order to find
what gpart show does not list (but can manipulate).
