ide-cd: fix oops when using growisofs
commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667 upstream
cdrom_read_capacity() will blindly return the capacity from the device
without sanity-checking it. This later causes code in fs/buffer.c to
oops.
Fix this by checking that the device is telling us sensible things.
