I recently made some bug fixes in nvmecontrol. It occurred to me that since nvmecontrol lacks any kyua tests, I should convert the informal testing I did into a more formal automated test. The test in this change should be considered just a starting point; it is neither complete nor thorough. While converting the test to ATF/kyua, I discovered a small bug in nvmecontrol; the nvmecontrol devlist command would always exit with an unsuccessful status. So I included the fix for that, too, so that the test won't fail. Reviewed by: imp@ MFC after: 3 days Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D24269
