examples/nvme_reserve: unregister the registrant key at last

Browse Source 
When testing the application, after release the reservation, the
registrant is still there, so we need to unregister the registrant
at last to restore the drive to a clean state.

Also set the CPTPL to 10b, it means Reservations are released
and registrants are cleared on a power on, we will move the tool
to test/nvme directory in following patch as this is only one
test case for NVMe reservation feature.
