bdev/nvme:Print multiple namespace attributes of nvme bdev in bdev_get_bdevs

Browse Source 
Current code only print the last namespace of nvme bdev, fix the print
way to show all the namespace.

And this patch will be prepared for the next patch to show io path status for multipath, like: which one is the primary or the backup, and the old status and current status,etc.
