atapi: abort transfers with 0 byte limits
We're supposed to abort on transfers like this, unless we fill
Word 125 of our IDENTIFY data with a default transfer size, which
we don't currently do.
This is an ATA error, not a SCSI/ATAPI one.
See ATA8-ACS3 sections 7.17.6.49 or 7.21.5.
If we don't do this, QEMU will loop forever trying to transfer
zero bytes, which isn't particularly useful.
