[PATCH] nvme-cli: return 0 if disconnect operation with cfg.nqn successfully

[Yi Zhang]

disconnect_by_nqn function will return the number of controllers
successfully disconnected, so change ret = 0 if disconnect operation
with nqn successfully.

$ ./nvme disconnect -n testnqn
NQN:testnqn disconnected 1 controller(s)
$ echo $?
1
