NAK. There's no guarantee that the next command after an error
will always be REQUEST_SENSE. Or is there?
I think we should just ignore the ERR bit when DRQ is set for PACKET
command.
Period. Possibly only for tape drives (since they all seem to do this),
and maybe not for non-tape drives.

Note also that if we already *know* that this ia an ATAPI device,
then we *know* that it will accept the PACKET opcode without error,
so there is no reason to even look at the ERR bit until after
the packet CDB has been transferred.
But I still think this should only apply to tapes for now.
