   Log Message:
   Add patch for CVE-2015-3456.

   fdc: force the fifo access to be in bounds of the allocated buffer

   During processing of certain commands such as FD_CMD_READ_ID and
   FD_CMD_DRIVE_SPECIFICATION_COMMAND the fifo memory access could
   get out of bounds leading to memory corruption with values coming
   from the guest.

   Fix this by making sure that the index is always bounded by the
   allocated memory.
