This fixes the error messages seen when attempting to use a SCSI cdrom
drive with
vmware. It is unclear to me whether this would do more harm than good,
since I don't
really know what the CDIOCREADSUBCHANNEL ioctl does. But it does look
righteous to me,
since without it, the 'track' variable in the bsdsc will be not be
initialized prior to
the fo_ioctl().

I can commit this if it would be easiest, though I think someone who
knows this area
better than me should comment first. :-)
