Upstream SVN r10244: "Fixed possible buffer overflow causing segfault
or memory corruption. The buffers are not large enough for the maximum
sector count in LBA48 mode. Now resetting buffer pointers after
processing a PRD (and move remaining data if necessary). This should
fix the SF bug items #3190970 and #3077616."
This happened to us when booting Debian 8 with a Linux 3.16 kernel
from "flat" or "volatile" disk images, in the end corrupting the VGA
card's ("theVga") internal state and segfaulting.

This change fixes another Bochs crash in the floppy controller,
triggered by one out of 670 million experiments in my current
campaign.
