Incorporate feedback from bde@ based on r252672 changes:

* Use 0/1 instead of sysexits.  Man pages are confusing on this topic,
  but 0/1 is sufficient for nvmecontrol.
* Use err function family where possible instead of fprintf/exit.
* Fix some typing errors.
* Clean up some error message inconsistencies.
