pktcdvd: remove warning on attempting to register non-passthrough dev
[ Upstream commit eb09b3cc464d2c3bbde9a6648603c8d599ea8582 ]
Anatoly reports that he gets the below warning when booting -git on
a sparc64 box on debian unstable:
...

Apparently debian auto-attaches any cdrom like device to pktcdvd, which
can lead to the above warning. There's really no reason to warn for this
situation, kill it.
