Subject: [PATCH] nvmetcli: create json file's dir first if it doesn't exist
The saveconfig operation will be failed as the /etc/nvmet dir
doesn't exist by default, so create it first before save operation.
$ ./nvmetcli
/> saveconfig
[Errno 2] No such file or directory: '/etc/nvmet/config.json.temp'
