rbd: drop dev registration check for new snap
By the time rbd_dev_snaps_register() gets called during rbd device
initialization, the main device will have already been registered.
Similarly, a header refresh will only occur for an rbd device whose
Linux device is registered. There is therefore no need to verify
the main device is registered when registering a snapshot device.
For the time being, turn the check into a WARN_ON(), but it can
eventually just go away.
