[PATCH] sbp2: add read_capacity workaround for iPod
Apple decided to copy some USB stupidity over to FireWire.
The sector number returned by iPods from read_capacity is one too many.
This may cause I/O errors, especially if the kernel is configured for EFI
partition support. We use the same workaround as usb-storage but have to
check for different model IDs.
