rbd-nbd: sscanf return 0 mean not-match.

When exec:  rbd-nbd map rbd/image --device /dev/image
The error message is:
rbd-nbd: failed to open device: /dev/image.

In fact, it should print:
rbd-nbd: invalid device path: /dev/image (expected /dev/nbd{num})

Meantime change help which make more understand.
